Selection Guide

ROHM’s BD45□□□G and BD46□□□G series are highly accurate, low current consumption reset IC series. Because the counter timer

delay circuit is built into those series, an external capacitor for the delay time setting is unnecessary. The lineup was established with tow

output types (Nch open drain and CMOS output) and detection voltages range from 2.3V to 4.8V in increments of 0.1V, so that the series may

be selected according the application at hand.
