Voltage detectors
VOLTAGE DETECTOR IC with counter timer
BD45XXXG 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
