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
Key Specifications
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.
Detection Voltage:
0.9V to 5.0V (Typ.)
0.1V step
Ultra-Low Current Consumption:
270nA (Typ.)
Time Delay Accuracy:
±30% (-40°C to +105°C, )
(CT pin capacitor ≥ 1nF)
Special Characteristics
Detection Voltage Accuracy:
