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.
