MAX16823AUE+

The MAX16823AUE+ is a high voltage, 3-channel linear high brightness LED driver with open LED detection in 16 pin TSSOP package. This 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. It 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.
