BD5223G-TR Datasheet, PDF (1/12 Pages) Rohm – Free Delay Time Setting CMOS Voltage Detector IC Series

Datasheet
Voltage Detector IC Series
Free Delay Time Setting
CMOS Voltage Detector IC Series
BD52xx series BD53xx series
●General Description
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.
●Features
„ Free delay time setting by external capacitor
„ Two output types (Nch open drain and CMOS output)
„ Ultra-low current consumption
„ Very small and low height package
●Key Specifications
