Voltage Detector IC Series

Counter Timer Built-in

CMOS Voltage Detector IC

BD45xxx series

BD46xxx series

●General Description

ROHM’s BD45xxx and BD46xxx series are highly

accurate, low current consumption Voltage Detector ICs.

Because the counter timer delay circuit is built into

these series, an external capacitor for the delay time

setting is unnecessary. The lineup was established with

low 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.

●Features

Counter Timer Built-in

No delay time setting external capacitor required

Ultra-low current consumption

Two output types (Nch open drain and CMOS output)

Package SSOP5 is similar to SOT-23-5 (JEDEC)
