Description
ROHM’s BD48xxx and BD49xxx series are highly
accurate, low-current Voltage Detector IC series. The
family includes BD48xxx devices with N-channel open
drain output and BD49xxx devices with CMOS output.
The devices are available for specific detection voltages
ranging from 2.3V to 6.0V in increments of 0.1V.
2.3V to 6.0V (Typ.),
0.1V steps
High accuracy detection voltage:
±1.0%
Ultra-low current consumption:
0.9µA (Typ.)
Operating temperature range:
