●General Description

ROHM’s BU42xx and BU43xx series are CMOS Voltage

Detector ICs with adjustable output delay. It is a

high-accuracy, low current consumption Voltage Detector

IC series with a built-in delay circuit. The lineup was

established with two output types (Nch open drain and

CMOS output) and detection voltages range from 0.9V to

4.8V in increments of 0.1V, so that the series may be

selected according to application.

●Features

Delay Time Controlled by external Capacitor

Two output types (Nch open drain and CMOS output)

Ultra-low current consumption

Wide operating temperature range

Very small and low height package

Package SSOP5 and SOP4 is similar to SOT-23-5

and SC-82 respectively (JEDEC)

●Applications

Circuits using microcontrollers or logic circuits that require

a reset.
