MB3771
DESCRIPTION
The Fujitsu MB3771 is designed to monitor the voltage level of one or two power supplies (+5 V and an arbitrary voltage) in a microprocessor circuit, memory board in large-size computer, for example. If the circuit's power supply deviates more than a specified amount, then the MB3771 generates a reset signal to the microprocessor. Thus, the computer data is protected from accidental erasure. Using the MB3771 requires few external components. To monitor only a +5 V supply, the MB3771 requires the connection of one external capacitor. The level of an arbitrary detection voltage is determined by two external resistors. The MB3771 is available in an 8-pin Dual In-Line, Single In-Line Package or space saving Flat Package.

FUNCTIONAL DESCRIPTIONS
Comparators Comp.A and Comp.B apply a hysteresis to the detected voltage, so that when the voltage at either the VSA or VSB pin falls below 1.23 V the RESET output signal goes to "low" level. Comp. B may be used to detect any given voltage(APPLICATION CIRCUIT 3 : Arbitrary Voltage Supply Monitor), and can also be used as a forced reset pin (with reset hold time) with TTL input (APPLICATION CIRCUIT 6 : 5V Power Supply Monitor with forced RESET input (VCC = 5 V) ). Note that if Comp.B is not used, the VSB pin should be connected to the VCC pin (APPLICATION CIRCUIT 1 : 5V Power Supply Monitor). Instantaneous breaks or drops in the power supply can be detected as abnormal conditions by the MB3771 within a 2 s interval. However because momentary breaks or drops of this duration do not cause problems in actual systems in some cases, a delayed trigger function can be created by connecting capacitors to the VSA or VSB pin (APPLICATION CIRCUIT 8 : Supply Voltage Monitoring with Delayed Trigger). Because the RESET output has built-in pull-up resistance, there is no need to connect to external pull-up resistance when connected to a high impedance load such as a CMOS logic IC. Comparator Comp. C is an open-collector output comparator without hysteresis, in which the polarity of input/ output characteristics is reversed. Thus Comp. C is useful for over-voltage detection (APPLICATION CIRCUIT 11 : Low Voltage and Over Voltage Detection (VCC = 5 V) ) and positive logic RESET signal output (APPLICATION CIRCUIT 7 : 5 V Power Supply Monitor with Non-inverted RESET), as well as for creating a reference voltage (APPLICATION CIRCUIT 10 : Reference Voltage Generation and Voltage Sagging Detection). Note that if Comp. C is not used, the VSC pin should be connected to the GND pin (APPLICATION CIRCUIT 1 : 5V Power Supply Monitor).

(1) When VCC rises to about 0.8V, RESET goes low. (2) When VCC reaches VS +VHYS, CT then begins charging. RESET remains low during this time (3) RESET goes high when CT begins charging. : TPO = CT x 10 5 (Refer to "CT pin capacitance vs. reset hold time" in "TYPICAL CHARACTERISTICS".) (4) When VCC level drops lower then VS, then RESET goes low and CT starts discharging. (5) When VCC level reaches VS + VHYS, then CT starts charging. In the case of voltage sagging, if the period from the time VCC goes lower than or equal to VS to the time VCC reaches VS +VHYS again, is longer than tPI, (as specified in the AC Characteristics), CT is discharged and charged successively. (6) After TPO passes, and VCC level exceeds VS + VHYS, then RESET goes high. (7) Same as Point 4. (8) RESET remains low until VCC drops below 0.8V. 3

(1) Case: VCC 18 V * Detection Voltage can be set by R1 and R2. Detection Voltage = (R1 + R2) x VSB/R2 * Connect Pin 7 to VCC when VCC less than 4.45 V. * Pin 7 can be opened when VCC greater than 4.45 V Power Dissipation can be reduced. Note : Hysteresis of 28 mV at VSB at termination is available. Hysteresis width dose not depend on (R1 + R2).

(2) Monitoring VCC > 18 V * Detection Voltage can be set by R1 and R2 Detection Voltage = (R1 + R2) x VSB/R2 * The RESET signal output is = 0V (low level) and = 5 V (high level). VCC voltage cannot be output. : : Do not pull up RESET to VCC. * Changing the resistance ratio between R4 and R5 changes the constant voltage output, thereby changing the voltage of the high level RESET output. Note that the constant voltage output should not exceed 18 V. * The 5 V output can be used as a power supply for control circuits with low current consumption. * In setting the R3 resistance level, caution should be given to the power consumption in the resistor.

NOTES ON USE
* Take account of common impedance when designing the earth line on a printed wiring board. * Take measures against static electricity. - For semiconductors, use antistatic or conductive containers. - When storing or carrying a printed circuit board after chip mounting, put it in a conductive bag or container. - The work table, tools and measuring instruments must be grounded. - The worker must put on a grounding device containing 250 k to 1 M resistors in series. * Do not apply a negative voltage - Applying a negative voltage of -0.3 V or less to an LSI may generate a parasitic transistor, resulting in malfunction.
