Description

M51951A,B/M51952A,B are semiconductor integrated circuits designed for detecting supply voltage and resetting all

types of logic circuits such as CPUs.

They include a built-in delay circuit to provide a retardation time (200 µs Typ).

They fined extensive applications, including battery checking circuit, level detecting circuit and waveform shaping

circuit.

Features

• Few external parts

• Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage):

0.6 V (Typ) at RL = 22 kΩ

• Wide supply voltage range: 2 V to 17 V

• Wide application range

Application

• Reset circuit of Pch, Nch, CMOS, microcomputer, CPU and MCU, Reset of logic circuit, Battery check circuit,

switching circuit back-up voltage, level detecting circuit, waveform shaping circuit, delay waveform generating

circuit, DC/DC converter, over voltage protection circuit

Recommended Operating Condition

• Supply voltage range: 2 V to 17 V
