●General Description
●Key Specifications
¢ Detection voltage:
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.
