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 (HB LEDs). 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 active-high, open-drain LEDGOOD output for open LED detection, a +3.4V (±5%) regulated output with 4mA output current capability, short-circuit and thermal protections. The MAX16823 is available in thermally enhanced 5mm x 5mm, 16-pin TQFN-EP and 16-pin TSSOP-EP packages and is specified over the -40°C to +125°C automotive temperature range.
