-40°C to +125°C Operating Temperature Range

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.

Product Details

The MAX16823 evaluation kit (EV kit) circuit demonstrates a current-controlled LED driver that uses the MAX16823 current regulator. The EV kit is configured to supply 50mA to each of the three output channels and the circuit features 3 series LEDs per channel. Output pads are provided at two channels to evaluate external LEDs rated up to 70mA. Additional output pads are available to evaluate LEDs rated up to 550mA (typ) on one of the channels. The MAX16823 EV kit requires a 6.5V to 16V, 1A power supply for proper operation. However, the MAX16823 IC can accept input voltages from 5.5V to 40V.

The MAX16823 EV kit features pulse-width modulation (PWM) dimming-control inputs and an open LED detection output. The MAX16823 EV kit is a fully assembled and tested printed circuit board (PCB).
