●General Description
●Key Specifications
Detection voltage:
ROHM’s BD48Exxx-M and BD49Exxx-M series are
highly accurate, low current consumption Voltage
Detector IC series. The line up 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.
