Voltage Detector IC Series

Low Voltage Standard

CMOS Voltage Detector ICs

BU48xx series BU49xx series

●General

Description

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.

●Features

Ultra-low current consumption

High accuracy detection, Ultra-low voltage detection

Two output types (Nch open drain and CMOS output)

Wide operating temperature range

Very small and low height package

Package SSOP5 and SOP4 is similar to SOT-23-5 and

SC-82 respectively (JEDEC)
