M51957A,B/M51958A,B are semiconductor integrated circuits for resetting of all types of logic circuits such as CPUs, and has the feature of setting the detection voltage by adding external resistance.

They include a built-in delay circuit to provide the desired retardation time simply by adding an external capacitor.

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

Features

• Few external parts

• Large delay time with a capacitor of small capacitance (td≈100 ms, at 0.33 μF) (M51957, M51958)

• 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
