BD46XXXG
BD45XXXG and BD46XXXG are series of high-accuracy detection voltage and low current consumption
VOLTAGE DETECTOR ICs adopting CMOS process. New lineup of 156 types with delay time circuit
have developed. Delay time is fixed in the IC due to the built-in counter timer to require no external
capacitor. Total 156 types of VOLTAGE DETECTOR ICs including BD45XXXG series (Nch open drain
output) and BD46XXXG series (CMOS output), each of which has 26 kinds in every 0.1V step (2.3~4.8V)
and three kinds of delay time (50msec, 100msec, 200msec) have developed.
Applications
Every kind of appliances with microcontroller and logic circuit
Features
1) Built-in delay time circuit
(Fixed delay time by the built-in ±10% of high-accuracy counter timer)
2) No external capacitor for setting delay time required
3) 3 kinds of delay time: 50msec(Typ.)(BD45XX5G,BD46XX5G)
100msec(Typ.)(BD45XX1G,BD46XX1G)
200msec(Typ.)(BD45XX2G,BD46XX2G)
4) Detection voltage: 2.3V ~ 4.8V 0.1V step
5) High-accuracy detection voltage: ±1.0%
6) Ultra low current consumption:0.85µA typ.
7) Output circuit: Nch open drain(BD45XXXG)
CMOS(BD46XXXG)
8) Package: SSOP5(SMP5C2)
9) Operating temperature range: -40°C ~ +105°C
