12 Channel Constant Current LED Driver IC - BD18377EFV-M

The BD18377EFV-M is a serial input controlled constant-current LED driver with 10V output rating. 6 bit current calibration is available for each output while a global PWM performs dimming on all outputs simultaneously. The BD18377EFV-M is able to perform diagnostic (open / short load / temperature) checks to detect LED failure and over temperature on chip. The settings of all internal registers can be read out to verify written information at any time.
