Every kind of appliances with microcontroller and logic circuit

BD45XXXG and BD46XXXG are series of high-accuracy detection voltage and low current consumption

VOLTAGE DETECTOR ICs adopting CMOS process.

have developed. Delay time is fixed in the IC due to the

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.

BD45XXXG

BD46XXXG
