CMOS Voltage Detector IC Series
BU42□□G series, BU42□□F series, BU42□□FVE series,
BU43□□G series, BU43□□F series, BU43□□FVE series
No.09006ECT02
●Description
ROHM CMOS reset IC series with adjustable output delay is a high-accuracy low current consumption reset IC series with
a built-in delay circuit. The lineup was established with two output types (Nch open drain and CMOS output) and detection
voltages 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
1) Detection voltage from 0.9V to 4.8V in 0.1V increments
2) Highly accurate detection voltage: ±1.0%
3) Ultra-low current consumption
4) Nch open drain output
5) Small surface package
(BU42□□G/F/FVE)and CMOS output (BU43□□G/F/FVE)
SSOP5: BU42□□G,BU43□□G
SOP4: BU42□□F,BU43□□F
VSOF5: BU42□□FVE,BU43□□FVE
●Applications
All electronics devices that use microcontrollers and logic circuits.
●Selection Guide
