FUJITSU MICROELECTRONICS DATA SHEET DS04-27400-11Ea ASSP For power supply applications BIPOLAR Power Supply Monitor MB3771 DESCRIPTION The Fujitsu Microelectronics 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.

C R Q S 1 CT 2 8 3 RESET OUTC MB3771 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). FUNCTION EXPLANATION VHYS VS VCC 0.8 V VCC CT 1 2 3 4 8 7 6 5 t RESET TPO RESET TPO t (1) (2) (3) (4) (5) (6) (7) (8) (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 MB3771 ABSOLUTE MAXIMUM RATINGS Parameter Rating Symbol Power supply voltage Input voltage Power dissipation Storage temperature Unit Min Max VCC -0.3 +20 V VSA -0.3 VCC + 0.3 ( < +20) V VSB -0.3 +20 V VSC -0.3 +20 V PD 200 (Ta 85 C) mW Tstg -55 +125 C WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings.

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.
