RNA51953A,B

Voltage Detecting, System Resetting IC Series

REJ03D0911-0100

Rev.1.00

Oct 10, 2008

Description

RNA51953A,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 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)

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

0.6 V (Typ) at R_L= 22 kΩ

•

Wide supply voltage range: 2 V to 17 V

Wide application range
