Voltage Detector IC Series for Automotive
Free Delay Time Setting
CMOS Voltage Detector IC Series
BD52Exxx-M series BD53Exxx-M series
●General Description
●Key Specifications
Detection voltage:
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
