ROHM Semiconductor BD83812EFV-M Automotive 12-Channel LED Driver IC

ROHM Semiconductor BD83812EFV-M Automotive 12-Channel LED Driver IC is a serial-in parallel-out controlled LED driver. With a 3-line serial input, it turns the 12-channel open-drain outputs on/off. The compact size makes the IC ideal for small spaces. ROHM Semiconductor BD83812EFV-M is ideal for indicator cluster panel applications.
