MB3761
VOLTAGE DETECTOR
Designed for voltage detector applications, the Fujitsu MB3761 is a dual
comparator with a built-in high precision reference voltage generator.
Outputs are open-collector outputs and enable use of the OR-connection
between both channels. Both channels have hysteresis control outputs.
Because of a wide power supply voltage range and a low power supply
current, the MB3761 is suitable for power supply monitors and battery
backup systems.
• Wide power supply voltage range: 2.5 V to 40 V
• Low power and small voltage dependency supply current: 250
µA
typical.
• Built-in stable low voltage generator: 1.20 V typical.
• Easy-to-add hysteresis characteristics.
• Package: 8-pin Plastic SIP Package (Suffix: -PS)
8-pin Plastic DIP Package (Suffix: -P)
8-pin Plastic FPT Package (Suffix: -PF)

are exceeded. Functional operation should be
restricted to the conditions as detailed in the operational sections
of this data sheet. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.

This device contains circuitry to protect the inputs against damage due
to high static voltages or electric fields. However, it is advised that
normal precautions be taken to avoid application of any voltage
higher than maximum rated voltages to this high impedance circuit.
