Datasheet
Voltage Detector IC Series
Counter Timer Built-in
CMOS Voltage Detector IC
BU45Kxxxx, BU46Kxxxx, BU45Lxxxx, BU46Lxxxx series
●General
Description
ROHM’s BU45xxxxx and BU46xxxxx series are highly
accurate, low current consumption voltage detector IC
series. Because the counter timer delay circuit is built-in,
an external capacitor for the delay time setting is
unnecessary. Two output types are available (Nch open
drain and CMOS output) and detection voltages range
from 2.3V to 4.8V in increments of 0.1V with fixed delay
time of 200ms and 400ms, that may be selected
according to application.
●Features
Counter Timer Built-in
No delay time setting capacitor required
Low current consumption
Two output types (Nch open drain and CMOS output)
Package SSOP3 is similar to SOT-23-3 (JEDEC)
