Preliminary Datasheet

RNA51955A, B

Voltage Detecting, System Resetting IC Series

R03DS0004EJ0202

Rev.2.02

Apr 19, 2011

Description

RNA51955A,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 a retardation time (200 s 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 k



Wide supply voltage range: 2 V to 17 V

Wide application range
