General Description

The BD18378EFV-M is a serial input controlled constant current LED driver with 8 V output rating.

6 bit current calibration is available for each output while a selected PWM input performs dimming on the corresponding output.

The BD18378EFV-M is able to perform diagnostic (open / short / temperature) checks to detect LED failure and over temperature on chip.
