BD48XXG/FVE series
BD49XXG/FVE series
Description
BD48XXG/FVE, BD49XXG/FVE are series of high-accuracy
detection voltage and low current consumption RESET ICs
adopting CMOS process. Total 152 types of RESET ICs including
BD48XXG/FVE series (Nch output drain output) and BD49XXG/
FVE series (CMOS output), each of which has 38 kinds in every
0.1V step (2.3~6.0V) have developed.
Features
1) Detection voltage: 0.1V step line-up 2.3~6.0V (Typ.)
2) High-accuracy detection voltage:±1.5% Max.
3) Ultra low current consumption: 0.8µA typ.
4) Nch open drain output (BD48XXG/FVE series),
CMOS output (BD49XXG/FVE series)
5) Small EMP5, SMP5C2 package
