BD52XXG/FVE series
BD53XXG/FVE series
Description
BD52XXG/FVE, BD53XXG/FVE are series of high-accuracy
detection voltage and low current consumption VOLTAGE
DETECTOR ICs adopting CMOS process.
New lineup of 152 types with delay time circuit have developed
in addition to well-reputed 152 types of VOLTAGE DETECTOR ICs.
Any delay time can be established by using small capacitor due to
high-resistance process technology.
Total 152 types of VOLTAGE DETECTOR ICs including
BD52XXG/FVE series (Nch open drain output) and BD53XXG/
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: 0.95µA (Typ.)
4) Nch open drain output (BD52XXG/FVE series),
CMOS output (BD53XXG/FVE series)
5) Small VSOF5
