●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.
●Features
Delay Time Controlled by external Capacitor
Two output types (N channel open drain and CMOS
output)
Ultra-low current consumption
Very small and low height package
Package SSOP5 is similar to SOT-23-5(JEDEC)
