●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)
