16-Port, 36V Constant-Current LED Driver with
LED Fault Detection and Watchdog
General Description
Features
The MAX6983 serial-interfaced LED driver provides 16
open-drain, constant-current-sinking LED driver outputs
rated at 36V. The MAX6983 operates from a 3V to 5.5V
supply. The MAX6983 supply and the LEDs’ supply can
power up in any order. The constant-current outputs
are programmed together to up to 55mA using a single
external resistor. The MAX6983 operates with a 25Mb,
industry-standard, 4-wire serial interface.
The MAX6983 includes circuitry that automatically
detects open-circuit LEDs. Fault status is loaded into the
serial-interface shift register when LE goes high and is
automatically shifted out on DOUT when the next data
transmission is shifted in.
The MAX6983 includes a fail-safe feature for safety-
related applications, which blanks the display if the ser-
ial interface fails. If the serial interface becomes
inactive for more than 1s, all driver output latches are
automatically cleared. This turns off all LEDs connected

The outputs remain off until the driver output latches are
updated with data turning them on, so recovery is auto-
matic if the transmission failure is temporary. The
watchdog function requires no software change to the

application driving the MAX6983.
The MAX6983 uses the industry-standard shift-register-
plus-latch-type serial interface. The driver accepts data
shifted into a 16-bit shift register using data input DIN
and clock input CLK. Input data appears at the output
DOUT 16 clock cycles later to allow cascading of multi-
ple MAX6983s. The latch-enable input, LE, loads the 16
bits of shift-register data into a 16-bit output latch to set
which LEDs are on and which are off. The output-
enable input, OE , gates all 16 outputs on and off, and is
fast enough to be used as a PWM input for LED intensi-

All versions operate from a 3V to 5.5V supply, and are
specified over the -40°C to +125°C temperature range.
