MAX6968 8-Port, 5.5V Constant-Current LED Driver

The MAX6968 serial-interfaced LED Driver provides eight open-drain, constant-current sinking LED Driver outputs rated at 5.5V. The MAX6968 operates from a 3V to 5.5V supply. The MAX6968 supply and the LEDs' supply or supplies may power up in any order. The constant-current outputs are programmed together to up to 55mA using a single external resistor. The MAX6968 operates with a 25Mb, industry-standard, 4- wire serial Interface The MAX6968 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 the output DOUT eight Clock cycles later to allow cascading of multiple MAX6968s. 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-bar Gates all eight 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 MAX6977 data sheet that automatically detects open-circuit LEDs For safety-related applications requiring a watchdog Timer refer to the MAX6978 data sheet that includes a fail-safe feature that blanks the Display if the serial Interface becomes inactive for more than 1s. The MAX6968 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 -40C to +125C temperature range.
