Free Delay Time Setting
CMOS Voltage Detector IC Series
BD52Exxx-M series BD53Exxx-M series
●General
Description
Rohm's BD52Exxx and BD53Exxx series are highly
accurate, low current consumption Voltage Detector
ICs with a capacitor controlled time delay. The line up
includes BD52Exxx devices with N-channel open drain
output and BD53Exxx 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, lightweight and thin package
Package SSOP5 is similar to SOT-23-5(JEDEC)
