M62032FP
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 APPLICATION Reset circuit of MPU, MCU and logics RECOMMENDED OPERATING CONDITION Supply voltage range ......................... 2 to 10V
