High-Voltage, 3-Channel Linear High-Brightness
LED Driver with Open LED Detection
General Description
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 indepen-
dent 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 detec-
tion, 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
