Voltage Detector IC Series

Low Voltage Standard

CMOS Voltage Detector ICs

BU48xx series BU49xx series

●General Description

●Key Specifications

 Detection voltage:

0.9V to 4.8V

0.1V steps

ROHM standard CMOS reset IC series is a high-accuracy,

low current consumption reset IC series. The lineup was

established with two output types (Nch open drain and

CMOS output) and detection voltage range from 0.9V to

4.8V in increments of 0.1V, so that the series may be

selected according to the application at hand.

 High accuracy detection voltage:

 Ultra-low current consumption:

 Operating temperature range:

●Package

±1.0%

0.55µA (Typ.)

-40°C to +125°C

●Features
