0.075A to 1.5A, Programmable Current-Limit Switch
General Description
The MAX4766 is a programmable current-limit switch that uses a proprietary control topology to provide a 10% accurate current limit. It operates from 2.25V to 4.5V input voltage. The current limit is resistor settable from 0.075A to 1.5A and features an adjustable soft-start function to control the output-voltage ramp rate, thereby limiting the inrush current. It also has an adjustable blanking time to accommodate various capacitive loads. If the load current is greater than the current-limit threshold, the current limiter handles the overcurrent situation in one of three ways depending on the option selected. It enters an autoretry mode (MAX4766A), latches off the switch (MAX4766B), or places the device in a continuous current-limit mode (MAX4766C). Additional safety features include thermal shutdown to prevent overheating and reverse-current blocking to prevent current from being driven back into the source. The MAX4766 is available in a tiny 8-pin 3mm x 3mm TDFN package and operates over the extended temperature range of -40C to +85C.

0.075A to 1.5A, Programmable Current-Limit Switch MAX4766
Detailed Description
The MAX4766 is a current-limit switch that operates from a 2.25V to 4.5V input voltage range and has a programmable current limit from 0.075A to 1.5A with a 10% accurate current limit. The device features an adjustable blanking time, an adjustable soft-start time, and an output indicator, FLAG, that notifies the processor when a fault condition is present (Figure 1). The MAX4766 is available in latch-off, autoretry, and continuous current-limit versions (see the Selector Guide).
Programmable Blanking Time (MAX4766A/MAX4766B)
The adjustable fault-blanking time feature of the MAX4766 ensures that no fault signal asserts during power-up or when there is a momentary short caused by hot-swapping a capacitive load. An external capacitor from SETB to GND sets the blanking time. When a short or load transient causes the device to enter current limit, an internal counter monitors the duration of the fault after the soft-start time elapses. For the MAX4766B, FLAG signal asserts low when load faults exceed the programmed blanking time (tBLANK). If the fault condition is removed before the programmed blanking time period has elapsed, the timer resets and the FLAG signal does not assert (see Figures 2a and 2b). Only current-limit and short-circuit faults are blanked.
Programmable Current Limit
A resistor from SETI to GND programs the current limit for the switch (see the Setting the Current Limit section). The MAX4766 increases the pass transistor's gate drive when the programmed current-limit value is reached. If the load current exceeds the current limit for longer than the tBLANK period, the switch either goes into autoretry, latches off, or stays in the continuous mode until the thermal limit is reached.

Programmable Soft-Start
The MAX4766 features an adjustable soft-start time to control the output voltage ramp rate, thereby limiting the inrush surge current. An external capacitor from SETS to GND sets the soft-start time. The value of the capacitor directly determines the typical soft-start time. Use the following formula to determine the soft-start time: Soft - Start(ms) = CSETS x 1ms 1nF
Leave SETS floating to choose 1ms minimum preset soft-start time.

LOAD CURRENT
When the forward current-limit threshold is exceeded, tBLANK timer begins counting. The timer resets if the overcurrent condition disappears before tBLANK has elapsed. The switch turns off and FLAG asserts if the overcurrent condition continues beyond the blanking time. Reset the switch by either toggling ON (Figure 2a) or cycling the input voltage (Figure 2b).
ON SWITCH STATUS OFF
Reverse-Current Protection
The MAX4766 features a reverse-current protection circuitry to limit the current back flow to 1A when the output voltage exceeds the input voltage by a 100mV. During this period, the switch turns off and FLAG asserts (MAX4766B/C) without waiting for tBLANK time to elapse. If at this point the output voltage drops below input +100mV, the switch turns on and FLAG deasserts (MAX4766B/C).
Figure 3. Autoretry Fault-Blanking Diagram
Autoretry (MAX4766A)
When the forward current-limit threshold is exceeded, the tBLANK timer begins counting (Figure 3). The timer resets if the overcurrent condition disappears before tBLANK has elapsed. A retry time delay (tRETRY) starts immediately after tBLANK has elapsed and during that time, the switch turns off. At the end of tRETRY, the switch turns on again. If the fault still exists, the cycle repeats. If the fault has been removed, the switch stays on. The autoretry feature saves system power in the case of an overcurrent or short-circuit condition. During tBLANK, when the switch is on, the supply current is at the current limit. During tRETRY, when the switch is off, the current through the switch is zero. Instead of observing the full load current, the switch sees the equivalent load current times duty cycle or: ISUPPLY = ILOAD
tBLANK tBLANK + tRETRY
Thermal Shutdown
A thermal-shutdown circuitry protects the devices from overheating. The switch turns off and FLAG goes (MAX4766B/C) low immediately (no fault blanking) when the junction temperature exceeds +150C. The MAX4766B (latch-off) does not turn on again until ON is cycled from high to low to high. The MAX4766A (autoretry) and the MAX4766C (continuous) turn the switch on again after the device temperature drops approximately +15C.
FLAG Indicator
FLAG is an open-drain fault indicator output and requires an external pullup resistor to a DC supply (usually IN). FLAG goes low when any of the following conditions occur: * The device is in current limit for more than the faultblanking period in the case of MAX4766B. * The device is in current limit in the case of MAX4766C (no blanking time). * The switch is in autoretry mode. * The OUT voltage is above the IN voltage by more than 100mV. * The die temperature exceeds the thermal-shutdown temperature limit of the +15C.
With a typical t BLANK = 15ms and typical t RETRY = 150ms, the duty cycle is 10%, which results in a 90% power savings over the switch being on the entire time.
Continuous Current Limit
In the continuous current-limit version of the MAX4766, the output stays at the current limit until the output load reduces. In this case, FLAG asserts as soon as there is current limit without waiting for blanking time and deasserts as soon as a short-circuit condition is removed. In this current mode, if the thermal power rating of the package is exceeded, the device will go into thermal shutdown and will not operate until the die temperature has cooled.

If the load capacitance is too large, then current may not have enough time to charge the capacitance and the device assumes that there is a faulty load condition. The maximum capacitive load value that can be driven from OUT is obtained by the following formula: CMAX =
IFWD _ MIN x tBLANK VIN
Layout and Thermal Dissipation
To optimize the switch response time to output shortcircuit conditions, it is very important to keep all traces as short as possible to reduce the effect of undesirable parasitic inductance. Place input and output capacitors as close as possible to the device (no more than 5mm). IN and OUT pins must be connected with short traces to the power bus. During normal operation, the power dissipation is small and the package temperature change is minimal. If the output is continuously shorted to ground at the maximum supply voltage, the operation of the switches with the autoretry option does not cause problems because the total power dissipated during the short is scaled by the duty cycle: PMAX =
VIN _ MAX x IOUT _ MAX x tBLANK tRETRY + tBLANK
Applications Information
Setting the Current Limit
A resistor from SETI to ground programs the currentlimit value for the MAX4766. Table 2 lists various current limits set by different resistor values. Use the following formula to calculate the current limit: RSETI =
112.5kV k ILIM( A)
Input Capacitor
Connect a capacitor from IN to ground to limit the input voltage drop during momentary output short-circuit conditions. A 2.2F ceramic capacitor with less than 0.2 ESR is adequate for most applications. Higher capacitor values further reduce the voltage drop at the input.
Attention must be given to the latch-off version of the MAX4766 where the latch-off condition must be manually reset by toggling ON from high to low. If the latchoff time duration is not sufficiently high, it is possible for the device to reach the thermal shutdown threshold and never be able to turn the device on until it cools down.
Chip Information
TRANSISTOR COUNT: 1544 PROCESS: CMOS
Output Capacitor
For stable operation over the full temperature range and over the full-programmable current-limit range, use a 2.2F capacitor with less than 0.2 ESR from OUT to ground.
