Datasheet

Voltage Detector IC Series

Free Delay Time Setting

CMOS Voltage Detector IC Series

BD52xx series

BD53xx series

●General Description

ROHM’s BD52xx and BD53xx series are highly

accurate, low current consumption reset IC series with

a built-in delay circuit. The lineup was established with

tow output types (Nch open drain and CMOS output)

and detection voltages range from 2.3V to 6.0V in

increments of 0.1V, so that the series may be selected

according the application at hand.

●Features

Free delay time setting by external capacitor

Two output types (Nch open drain and CMOS output)

Ultra-low current consumption

Very small and low height package

●Key Specifications

Detection voltage:

2.3V to 6.0V (Typ.)
