Voltage Detector IC Series
Free Delay Time Setting
CMOS Voltage Detector IC Series
BD52xx series
General Description
Rohm's BD52xx and BD53xx series are highly
accurate, low current consumption Voltage Detector
ICs with a capacitor-controlled time delay. The line up
includes BD52xx devices with N channel open drain
output and BD53xx devices with CMOS output. The
devices are available for specific detection voltages
ranging from 2.3V to 6.0V in increments of 0.1V.
