Datasheet
Voltage Detector (Reset) IC Series for Automotive Application
Free Time Delay Setting
CMOS Voltage Detector (Reset) IC
BD52xx-2C Series and BD53xx-2C Series
General Description
ROHM's BD52xx-2C and BD53xx-2C series are highly
accurate, low current consumption Voltage Detector
ICs with a capacitor controlled time delay. The lineup
includes N-channel open drain output (BD52xx-2C)
and CMOS output (BD53xx-2C) so that the users can
select depending on the application. The devices are
available for specific detection voltage ranging from
0.9V to 5.0V with 0.1V increment.
The time delay has ±50% accuracy in the overall
operating temperature range of -40°C to 125°C.
