MB3773 Datasheet (Cypress Semiconductor)

MB3773, Power Supply Monitor

MB3773 Power Supply Monitor with Watch-Dog Timer MB3773 generates the reset signal to protect an arbitrary system when the power-supply voltage momentarily is intercepted or decreased.

It is IC for the power-supply voltage watch and “Power on reset” is generated at the normal return of the power supply.

MB3773 sends the microprocessor the reset signal when decreasing more than the voltage, which the power supply of the system specified, and the computer data is protected from an accidental delet

MB3773 Features

* Precision voltage detection (VS = 4.2 V  2.5%)

* Detection threshold voltage has hysteresis function

* Low voltage output for reset signal (VCC = 0.8 V Typ)

* Precision reference voltage
