Voltage Detector (Reset) IC Series for Automotive Application
Free Time Delay Setting
CMOS Voltage Detector (Reset) IC
BD52xx-2M Series and BD53xx-2M Series
General Description
ROHM's BD52xx-2M and BD53xx-2M 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-2M)
and CMOS output (BD53xx-2M) 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 ±30% accuracy in the overall
operating temperature range of -40°C to 105°C.
Special Features
AEC-Q100 Qualified (Note1)
