The A8514 is a fault-tolerant LED driver for automotive LCD backlighting, integrating a boost converter and four 80 mA LED current sinks. It operates from a 5 to 40 V supply and drives up to 48 LEDs in four strings of 12 series LEDs, with 0.7% to 0.8% LED-to-LED matching accuracy. It supports PWM and analog dimming at 5000:1 ratio at 200 Hz, and synchronizes switching from 580 kHz to 2.3 MHz to avoid the AM band. It includes protection against shorted LEDs, overvoltage, overtemperature, and open or shorted resistors, and drives an external PMOS input disconnect. The device is in a 20-pin TSSOP with an exposed thermal pad and is AEC-Q100 qualified. This part is a Last Time Buy with no samples available and orders restricted to existing applications.
