Datasheet

Voltage Detector IC Series for Automotive

Counter Timer Built-in

CMOS Voltage Detector IC

BD45Exxxx-M series BD46Exxxx-M series

●Key Specifications

 Detection voltage:

●General Description

2.3V to 4.8V (Typ.)

0.1V steps

±1.0%

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.

 High accuracy detection voltage:

 Ultra-low current consumption:

 Operating temperature range:

 Three internal, fixed delay time:

0.85µA (Typ.)

-40°C to +105°C

50ms

100ms

200ms

●Package

SSOP5

2.90mm x 2.80mm x 1.25mm

●Features

 Counter Timer Built-in

 No delay time setting capacitor required

 Ultra-low current consumption

●Applications

Circuits using microcontrollers or logic circuits that

require reset for automotive applications (car

navigation, car audio, meter panel, exterior lamp etc.)

 Two output types (Nch open drain and CMOS output)

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

 AEC-Q100 Qualified
