Voltage Detector IC Series for Automotive
Counter Timer Built-in
CMOS Voltage Detector IC
BD45Exxxx-M series BD46Exxxx-M series
General Description
ROHM’s BD45Exxxx-M and BD46Exxxx-M series are
highly accurate, low current consumption Voltage
Detector 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 two 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 to application.
Features
Counter Timer Built-in
No delay time setting capacitor required
