Mitsubishi M62032FP Datasheet

VOLTAGE DETECTING, SYSTEM RESETTING IC

GENERAL DESCRIPTION

The M62032FP is an IC for detection of two different input
voltages to reset almost all logic circuits including MCU.
It contains a delay circuit with which any delay time can be
obtained only by adding an external capacitor.
The IC is widely applicable to a battery check circuit, a level
detection circuit, a waveform shaping circuit, etc.

FEATURES

• A small number of external components

• Built-in 2 input voltage detection circuits

• Wide supply voltage range ............... 2 to 10V

• Small 8-pin package

• Open collector output
