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 Voltage Detector

ICs with a capacitor-controlled time delay. The line up

includes BD52xx devices with N channel open drain

output and BD53xx devices with CMOS output. The

devices are available for specific detection voltages

ranging from 2.3V to 6.0V in increments of 0.1V.

●

Features

Delay Time Controlled by external Capacitor

Two output types (N channel open drain and CMOS

output)

Ultra-low current consumption

Very small and low height package

Package SSOP5 is similar to SOT-23-5(JEDEC)
