BD94130EFV-ME2 is an automotive LED driver series embedded 24- channel constant current driver with 12bit PWM dimming and max 8-line switch controllers. This device can set LED constant current value by setting external ISET resistor. Communication with µ-controller via SPI is feasible. Application includes cluster, centre infotainment display, other automotive backlights.
