CMOS Voltage Detector IC Series
BD52xx series BD53xx series
●General Description
●Key Specifications
Detection voltage:
ROHM’s BD52xx and BD53xx series are highly
accurate, low current consumption reset IC series with
a built-in delay circuit. The lineup was established with
tow output types (Nch open drain and CMOS output)
and detection voltages range from 2.3V to 6.0V in
increments of 0.1V, so that the series may be selected
according the application at hand.
