VOLTAGE DETECTOR
MB3761
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.
