BD45XXXGBD46XXXG

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.
