Advanced 12 Channel Constant Current LED Driver IC BD18378EFV-M 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. Fault detection is performed also during LED deactivated state. The settings of all internal registers can be read out to verify written information at any time. Features  AEC-Q100 Qualified (Note1)  Current capability: 50mA per output channel.  4-line SPI Control.  External resistor current setting.  Limp Home capability.  PWM dimming 0.2-99.
