Voltage Detector IC Series
Standard CMOS
Voltage Detector IC
BD48xxx series BD49xxx series
●General Description
ROHM’s BD4 8xxx and B D49xxx seri es are hig hly
accurate, lo w current cons umption reset IC series. T he
line u p incl udes BD48 xxx de vices with N chan nel o pen
drain output a nd BD4 9xxx d evices with C MOS output.
The devices are available for specific detecti on voltages
ranging from 2.3V to 6.0V in increments of 0.1V.
