s FUNCTIONAL DESCRIPTION
1. Power Supply Control Unit
(1) Reference Voltage Block The reference voltage circuit uses the voltage supplied from the VCC terminal (pin 40) and generates a temperature compensated reference voltage (1.23 V (Typ.)), for use as the reference voltage for the power supply control unit. (2) Constant Voltage Control Block (REG1) This constant voltage control block (REG1) uses the voltage supplied from the reference voltage and generates the output voltage (2.5 V) from the OUT1 terminal (pin 29). An external load current can be obtained from the OUT1 terminal up to a maximum of 70 mA. Also, by setting the ICONT terminal (pin 36) to "L" level the MB3893A can be placed in low current consumption (standby) mode. In standby mode, REG1 is On with a maximum output load of 500 A, and REG3 is Off. In this state, ripple rejection and noise levels are not assured. (3) Constant Voltage Control Block (REG2) This constant voltage control block (REG2) uses the voltage supplied from the reference voltage and generates the output voltage (1.8 V) from the OUT2 terminal (pin 30). An external load current can be obtained from the OUT2 terminal up to a maximum of 50 mA. Also, by setting the ICONT terminal (pin 36) to "L" level the MB3893A can be placed in low current consumption (standby) mode. In standby mode, REG2 is On with a maximum output load of 500 A, and REG3 is Off. In this state, ripple rejection and noise levels are not assured. (4) Constant Voltage Control Block (REG3) This constant voltage control block (REG3) uses the voltage supplied from the reference voltage and generates the output voltage from the OUT3 terminal (pin 27). An external load current can be obtained from the OUT3 terminal up to a maximum of 70 mA. Also, the output voltage can be changed to 1.9V or 2.2 V by mask option. (5) Constant Voltage Control Block (REG4) This constant voltage control block (REG4) uses the voltage supplied from the reference voltage and generates the output voltage (2.5 V) from the OUT4 terminal (pin 22). An external load current can be obtained from the OUT4 terminal up to a maximum of 60 mA. Also, by setting the ICONT terminal (pin 36) to "L" level the MB3893A can be placed in low current consumption (standby) mode. In standby mode, REG4 is On with a maximum output load of 500 A, and REG3 is Off. In this state, ripple rejection and noise levels are not assured. (6) VREF1M This block takes the reference voltage (1.23 V (Typ.)) generated by the reference voltage block, and uses a voltage follower to produce a temperature compensated reference voltage (1.23 V (Typ.)) at the VREF1M terminal (pin 10). Also, an external load current can be obtained from the VREF1M terminal up to a maximum of 1 mA. (7) ON/OFF Control Block This block controls regulator On/Off switching according to the voltage levels of the POFF terminal (pin 18), CONT2 terminal (pin 26), CONT5 terminal (pin 6), ICONT terminal (pin 36), DRST terminal (pin 5), XON terminal (pin 11), ONOFF1 terminal (pin 9), ONOFF2 terminal (pin 17), and CONT1 terminal (pin 14). 24
MB3893A
(8) POR Block When the output voltage from the regulator (OUT1) exceeds 2.3 V (Typ.), the XRST terminal (pin 35) goes to "H" level following a delay time (85 ms (Typ.)) set by capacitors (0.1 F (Typ.)) connected between the C1 terminal (pin 7) and the GND1 terminal (pin 8) and GND2 terminal (pin 39). Also, when the regulator (OUT1) output voltage falls below 2.2 V ((Typ.)), the XRST terminal goes back to "L" level. (9) Initial Power Supply Drop Detection 1 This block controls MB3893A operation when VCC startup occurs at VCC voltage of 2.0V (Typ.) or greater. When VCC voltage exceeds 2.75V (Typ.) the VCONT terminal (pin 16) voltage goes to "H" level, and the regulated voltage is output from the OUT1 terminal (pin 29), OUT2 terminal (pin 30), and OUT4 terminal (pin 22). When VCC voltage falls below 3.1V (Typ.), the voltage at the OUT1, OUT2, and OUT4 terminals is outside of rated values. Then when VCC voltage falls below 2.5V (Typ.), the VCONT terminal (pin 16) voltage goes to "L" level, and the OUT1, OUT2, and OUT4 terminals go to "L" level (regulator "OFF" state). Hereafter this is referred to as "L" level. As long as the VCC voltage rises again before dropping below 2.0V (Typ.), the VCONT pin voltage will return to "H" level once VCC reaches 3.5 V (Typ.), and the regulated voltage is output from the OUT1, OUT2, and OUT4 terminals. (10) Transient Power Supply Drop Detection 2 This block detects two types of power supply drop times according to the time constants CR1 and CR2, and produces the related output at the VBDET1 terminal (pin 34) and VBDET2 terminal (pin 33).
2. Charge Control Block
The charge control block checks VIN, battery voltage, and battery temperature before charging. If the results are within normal ranges, charging begins. During charging, the charging times and current levels are varied according to battery voltage. The VIN and battery temperature are monitored, and if either exceeds the normal range charging is stopped. Conditions are then monitored for a fixed time (16 min (Typ.)) and a resume charging/ abnormal termination determination is made. The MB3893A also provides an overcharge protection function, as well as a function that stops charging when a rise in IC junction temperature is detected. Once charging has stopped due to any of these abnormal conditions, it can be resumed by re-input of VIN, or by removing and replacing the battery. (1) Constant Current/Constant Voltage Charging The MB3893A applies a constant current charge according to the battery voltage level, selecting over discharge recovery charging (2.1 mA (Typ.)), preliminary charging (80 mA (Typ.)) or rapid charging (590 mA (Typ.)). Once battery voltage reaches 4.1 V (4.2 V), constant voltage charging is applied until the charge current falls to 53 mA (Typ.) at constant voltage. (2) Timer Function The timer switches the charging time according to the battery voltage level, between over discharge recovery charging (15 s (Typ.)), preliminary charging (16 min (Typ.)), and rapid charging (240 min (Typ.)). (3) Temperature/AC Adapter Voltage Detection This block detects the battery temperature and AC adapter voltage, and stops charging if either is outside of the normal charging range. If normal conditions are restored within a set time (16 min (Typ.)), charging is resumed, otherwise an abnormal termination is determined. (4) Over-Charge Protection If battery voltage exceeds 4.3 V (Typ.) this block determines an abnormal condition, and stops charging. 25
MB3893A
s SETTING THE XON DELAY TIME
When the XON terminal (pin 11) voltage changes from "H" to "L" level, the VCONT signal (pin 16) rises. The time constant of the capacitor (CRC1) and resistor (RRC1) connected to the RC1 terminal (pin 15) determine the delay time before the rise of the VCONT signal (pin 16). XON delay time : tXON (ms) = 598.3 x CRC1 (F) :
s SETTING THE XRST DELAY TIME
The time constant of the capacitor (CC1) connected to the C1 terminal (pin 7) determines the delay time between the rise of the OUT1 terminal (pin 29) voltage above 2.3 V (Typ.) and the rise of the XRST terminal (pin 35) voltage. XRST delay time : tPOR (s) = 1.23 (V) x CC1 (F) : 1.45 (A)
s SETTING THE POWER SUPPLY DROP DETECTION TIME
When the VCC terminal (pin 40) voltage falls below 2.0 V (Typ.) the CR1 terminal (pin 12) and CR2 terminal (pin 13) are opened, and the capacitors (CCR1, CCR2) connected to the CR1 and CR2 terminals are discharged through the respective resistors (RCR1, RCR2). The discharge time (cutoff detection time) of the CR1 and CR2 pins can be set according to the time constants of the capacitors and resistors connected to the CR1 and CR2 terminals respectively, between 0.89 V (Typ.) to 0.51 V (Typ.). Cutoff detection time : tDET1 (s) = -CCR1 (F) x RCR1 (M) x ln (0.51 (V) /0.89 (V) ) : tDET2 (s) = -CCR2 (F) x RCR2 (M) x ln (0.51 (V) /0.89 (V) ) :
s BATTERY TEMPERATURE DETECTION
The battery temperature sensor uses the thermistor shown below. The thermistor temperature coefficient is set by the following formula. Thermistor temperature coefficient : B = T1 : 276 (K) = 3 ( C) R1 : 23.27 (k) T2 : 321 (K) = 48 ( C) R2 : 4.026 (k) lnR1 - lnR2 = 3454 (K) 1 / T1 - 1 / T2

s SETTING THE OSCILLATOR PERIOD
The oscillator period is set by connecting a timing capacitor (COSC) to the COSC terminal (pin 44), and a timing resistor (ROSC) to the ROSC terminal (pin 45). Oscillator period : tOSC (s) = 1.073 x 10-3 x {COSC (pF) + CP (pF) } x ROSC (k) : CP : Board capacitor = 19 (pF) :
s SETTING THE OVER DISCHARGE RECOVERY CHARGE TIME
When battery voltage is less than the preliminary charge start voltage (2.115 V (Typ.)), the over discharge recovery charge time is set by the following formula. Over discharge recovery charge time : tRECO (s) = TOSC (s) x 221 :
s PRELIMINARY CHARGE TIME
When battery voltage is higher than the preliminary charge start voltage (2.115 V (Typ.)), and lower than the fast charge start voltage (3.115 V (Typ.)), the preliminary charge time is set by the following formula. Preliminary charge time : tPC (min) = : tOSC (s) x 227 60
s RAPID CHARGE TIME
When battery voltage is higher then the fast charge start voltage (2.115 V (Typ.)), and lower than the overvoltage stop voltage (4.325 V (Typ.)), the rapid charging time is determined by the following formula.
27 28 29 30 Rapid charging time : tFT (min) = tOSC (s) x (2 + 2 + 2 + 2 ) : 60

s POWER SUPPLY CONTROL UNIT TIMING CHART
1. Power Supply Drop Detection 1
As Figure 1 shows, there is a "don't care zone" where VCC voltage is below 2 V. When VCC voltage is above VCCE voltage (2.75 V (Typ.)), the VCONT terminal (pin 16) goes to "H" level, and after a delay time (tR) the OUT1 terminal (pin 29), the OUT2 terminal (pin 30), and the OUT4 terminal (pin 22) output their regulated voltages. When VCC voltage falls below VCCD voltage (2.50 V (Typ.)), a power supply drop detection is determined and the VCONT terminal goes to "L" level, and therefore the OUT1, OUT2, and OUT4 terminals also go to "L" level. If the VCC voltage rises again before falling below 2 V, the OUT1, OUT2, and OUT4 terminals will once again output their regulated voltages once VCC exceeds the VCCR voltage (3.50 V (Typ.))

2. Delayed ON Input Operation (XON)
As Figure 2 shows, When the XON terminal (pin 11) changes from "H" to "L" level, the capacitor connected to the RC1 terminal (pin 15) starts to charge. After the delay interval (tXON : 600ms (Typ.)), once the RC1 terminal exceeds the internal threshold voltage the VCONT terminal (pin 16) goes to "H" level, and the OUT1 (pin 29), OUT2 (pin 30), OUT3 (pin 27), and OUT4 (pin 22) terminals then output their respective regulated voltages after a delay interval (tR1). Note however that for the OUT3 terminal to output its regulated voltage, it is necessary for the CONT2 terminal (pin 26) to be at "L" level. Also, for the XON pin to return from "L" level to "H" level, a delay interval (tXON : 600 ms (Typ.)) is required.

Note however that for the OUT3 terminal to output its regulated voltage, it is necessary for the CONT2 terminal (pin 26) to be at "L" level. Also once the OUT1, OUT2, OUT3, and OUT4 terminals have started to output their regulated voltages, the voltage at the OUT1, OUT2, OUT3, and OUT4 terminals will not change even if the CONT1 terminal goes from "L" to "H" level, or from "H" level to "L" level.

Also, a minimum of 10 s is required to set the POFF signal to "H" level.

As Figure 6 shows, when the ONOFF1 terminal (pin 9) goes from "L" level to "H" level, the VCONT terminal (pin 16) goes to "H" level, and the OUT1 (pin 29), OUT2 (pin 30), OUT3 (pin 27), and OUT4 (pin 22) terminals output their respective regulated voltages. The next time the POFF terminal (pin 18) goes from "L" level to "H" level, the VCONT terminal (pin 16) goes to "L" level, and the OUT1 (pin 29), OUT2 (pin 30), and OUT4 (pin 22) terminals go to "L" level. Then when the ONOFF2 terminal (pin 17) goes from "L" level to "H" level, the VCONT terminal returns to "H" level, and the OUT1, OUT2, OUT3 and OUT4 terminals output their respective regulated voltages. The next time the POFF terminal goes from "L" level to "H" level, the VCONT terminal goes to "L" level, and the OUT1, OUT2, and OUT4 terminals go to "L" level. Then when the ONOFF1 terminal goes from "L" level to "H" level, the VCONT terminal returns to "H" level, and the OUT1, OUT2 and OUT4 terminals output their respective regulated voltages. The next time the POFF terminal goes from "L" level to "H" level, the VCONT terminal goes to "L" level, and the OUT1, OUT2, and OUT4 terminals go to "L" level. Then when the ONOFF2 terminal goes from "H" level to "L" level, the VCONT terminal returns to "H" level, and the OUT1, OUT2 and OUT4 terminals output their respective regulated voltages. The next time the POFF terminal goes from "L" level to "H" level, the VCONT terminal goes to "L" level, and the OUT1, OUT2, and OUT4 terminals go to "L" level.

As Figure 8 shows, when the VCONT terminal (pin 16) goes from "L" level to "H" level, the OUT1 terminal (pin 29) outputs its regulated voltage. Then, after a delay interval (85 ms (Typ.)) the XRST terminal (pin 35) goes to "H" level. If after the XRST terminal has gone to "H" level the ICONT terminal (pin 36) goes to "L" level, the MB3893A goes into standby mode, reducing the IC internal current consumption. When the ICONT terminal returns to "H" level normal operation is restored. When the VCONT terminal goes from "H" level to "L" level, the OUT1 terminal goes to "L" level. At this time the XRST terminal also goes to "L" level.

9. Power Supply Drop Detector 2 (Initial power supply detector/power supply drop detector)
a) t > 10 s The MB3893A power supply drop detection intervals are set to tDET1 (10 s (Typ.)) and tDET2 (1.5 s (Typ.)) so that, as shown in Figure 9(a), when VCC goes from "H" level to "L" level, the OUT1 (pin 29), OUT2 (pin 30), and OUT4 (pin 22) terminals go to "L" level, and the XRST terminal (pin 35) also goes to "L" level. At this time, the VBDET1 terminal (pin 34) and VBDET2 terminal (pin 33) also go to "L" level. When VCC drops for a fixed interval (t > 10 s), and then returns to "H" level, the OUT1, OUT2, and OUT4 terminals after a delay interval (tR2) output their regulated voltages, and the XRST terminal after a delay interval (tPOR) goes to "H" level. During the interval between the VCC drop and XRST terminal return to "H" level the VBDET1 terminal and VBDET2 terminal are in undefined state. Also once the XRST terminal returns to "H" level the VBDET1 terminal is at "L" level and the VBDET2 terminal is at "H" level. At this time, if the DRST terminal (pin 5) goes to "H" level, the VBDET1 terminal also goes to "H" level. Note that the DRST terminal must be at "H" level for at least an interval of 10 s.

At this time, the VBDET1 terminal (pin 34) and VBDET2 terminal (pin 33) also go to "L" level.

Also once the XRST terminal returns to "H" level the VBDET1 terminal is at "H" level and the VBDET2 terminal is also at "H" level. At this time, if the DRST terminal (pin 5) goes to "H" level, the VBDET1 and VBDET2 terminals remain at "H" level. Note that the DRST terminal must be at "H" level for at least an interval of 10 s.

s ABOUT CAPACITOR CONNECTED TO VCC PIN
When the VCC voltage exceeds 2.75 V (Typ.), the VCONT terminal (pin 16) goes to "H" level, and the OUT1 (pin 29), OUT2 (pin 30), and OUT4 (pin 22) terminals rise. When each of these respective OUT terminals rises, a rush current flows to the capacitor connected to that OUT terminal. At this time the internal impedance of the battery causes VCC to drop, and if VCC voltage goes below 2.5 V (Typ.), the OUT terminal voltage regurns to "L" level (regulator OFF mode).t is necessary to set the capacitor connected between VCC and GND taking into consideration the internal impedance of the battery, so that the VCC drop does not go below 2.5 V.
