BU48□□G Series, BU48□□F Series, BU48□□FVE Series,
BU49□□G Series, BU49□□F Series, BU49□□FVE Series
No.11006EDT01
●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
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 (BU48□□G/F/FVE)and CMOS output (BU49□□G/F/FVE)
5) Small surface package SSOP5: BU48□□G, BU49□□G
SOP4: BU48□□F, BU49□□F
VSOF5: BU48□□FVE, BU49□□FVE
●Applications
All electronics devices that use microcontrollers and logic circuits.
●Selection Guide
No.
