8-Port, 36V Constant-Current LED Driver

with LED Fault Detection and Watchdog

General Description

The MAX6980 serial-interfaced LED driver provides

eight open-drain, constant-current-sinking LED driver

outputs rated at 36V. The device operates from a 3V to

5.5V supply. The MAX6980 supply and the LEDs’ sup-

ply can power up in any order. The constant-current

outputs are programmed together up to 55mA using a

single external resistor. The MAX6980 operates with a

25Mbps, industry-standard, 4-wire serial interface.

The MAX6980 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 MAX6980 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

to the outputs. The shift register data is not disturbed.

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 MAX6980.

The MAX6980 uses the industry-standard shift-register-

plus-latch-type serial interface. The driver accepts data

shifted into an 8-bit shift register using data input DIN

and clock input CLK. Input data appears at output

DOUT eight clock cycles later to allow cascading of

multiple MAX6980s. The latch-enable input, LE, loads

the 8 bits of shift register data into an 8-bit output latch

to set which LEDs are on and which are off. The output-

enable input,

OE,

gates all eight outputs on and off,

and is fast enough to be used as a PWM input for LED

intensity control.

The MAX6980 is one of a family of 10 shift-register-plus-

latch-type LED drivers. The family includes 8-port and

16-port types, with 5.5V- or 36V-rated LED outputs, with

and without open-circuit LED detection and watchdog.

All versions operate from a 3V to 5.5V supply, and are

specified over the -40°C to +125°C temperature range.
