The MAX16823 three-channel LED driver operates from a 5.5V to 40V input voltage range and delivers up to 100mA per channel to one or more strings of high-brightness LEDs (HBLEDs). Each channel's current is programmable using an external current-sense resistor in series with the LEDs. Three DIM inputs allow a wide range of independent pulsed dimming in addition to providing the on and off control of the outputs. Wave-shaping circuitry reduces EMI while providing fast turn-on and turn-off times. The MAX16823 is well suited for automotive applications requiring a high-voltage input and is able to withstand load-dump events up to 45V. On-board pass elements minimize external components while providing 5% LED current accuracy. Additional features include an activehigh, open-drain LEDGOOD output for open LED detection, a +3.4V (5%) regulated output with 4mA output current capability, short-circuit and thermal protections.
