Datasheet

Voltage Detector IC Series

Low Voltage Free Delay Time Setting

CMOS Voltage Detector IC Series

BU42xx series BU43xx series

●General Description

●Key Specifications

¢ Detection voltage:

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.

0.9V to 4.8V (Typ.)

0.1V steps

¢ High accuracy detection voltage:

¢ Ultra-low current consumption:

¢ Operating temperature range:

●Package

0.55µA (Typ.)

-40°C to +125°C

SSOP5:

2.90mm x 2.80mm x 1.25mm

2.00mm x 2.10mm x 0.95mm

1.60mm x 1.60mm x 0.60mm

●Features

¢ Delay Time Controlled by external Capacitor

¢ Two output types (Nch open drain and CMOS output)

¢ Ultra-low current consumption

SOP4:

VSOF5:

¢ 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)
