The A8517 is a discontinued wide input voltage, fault-tolerant, multi-channel LED driver with an I2C interface, designed for automotive applications such as infotainment, instrument clusters, and head-up displays. It integrates a boost converter with a 40 V load-dump tolerance and ten independently programmable LED current sinks capable of up to 60 mA per channel. The device is AEC-Q100 qualified, operates from 4.5 to 36 V, and features comprehensive diagnostics, programmable PWM dimming up to 10,000:1 at 100 Hz, and polyphase PWM to reduce flicker and input ripple. It is packaged in a 28-pin TSSOP with an exposed thermal pad. The A8517KLPTR-T variant is specified for an operating ambient temperature range of -40 to 125 °C and uses 100% matte tin plating on a 28-pin TSSOP package.
