Description

The M62030FP is a voltage threshold detector designed for detection of an input voltage/supply voltage and generation

of a system reset pulse for almost all logic circuits such as microcontroller.

In contains a delay circuit which provides 200

µs (Typ) delay and 4 modes of delays (25 ms, 50 ms, 100 ms, 200 ms

(Typ)) in the input voltage detection type and in the supply voltage detection type, respectively.

Features

• Built-in two functional circuits for detecting voltage

• Built-in delay circuit to provide long delay time (without external delay capacitors)

• Selectable four modes of delay time (25 ms, 50 ms, 100 ms, 200 ms (Typ))

• Few external parts

• Small 8-pin SOP package

Application

• Reset circuits of MCU, MPU and logics

Recommended Operating Condition

• Supply voltage range: 2 V to 10 V
