16-Port, 5.5V Constant-Current LED Driver
General Description
The MAX6969 serial-interfaced LED driver provides 16
open-drain, constant-current-sinking LED driver outputs
rated at 5.5V. The MAX6969 operates from a 3V to 5.5V
supply. The MAX6969 supply and the LEDs’ supply or
supplies can power up in any order. The constant-cur-
rent outputs are programmed together to up to 55mA
using a single external resistor. The MAX6969 operates
with a 25Mb, industry-standard, 4-wire serial interface.
The MAX6969 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 DOUT
output 16 clock cycles later to allow cascading of multi-
ple MAX6969s. 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, OE,gates all 16 outputs on and off, and is fast
enough to be used as a PWM input for LED intensity
control.
For applications requiring LED fault detection, refer to
the MAX6984*, which automatically detects open-circuit
LEDs.
For safety-related applications requiring a watchdog
timer, refer to the MAX6979, which includes a fail-safe
feature that blanks the display if the serial interface
becomes inactive for more than 1s.
The MAX6969 is one of a family of 12 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.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
