Description

Electronic Component Model: BD45271G-TR is a voltage detector IC with a counter timer. It belongs to the supervisors product category. It is a high-accuracy detection voltage and low current consumption voltage detector IC adopting CMOS process. It comes in a new lineup of 156 types with a delay time circuit. The delay time is fixed in the IC due to the built-in counter timer, eliminating the need for an external capacitor. The total of 156 types includes BD45XXXG series (Nch open drain output) and BD46XXXG series (CMOS output), each with 26 kinds in every 0.1V step (2.3~4.8V) and three kinds of delay time (50msec, 100msec, 200msec).
