8-Port, 36V Constant-Current LED Driver
General Description
The MAX6970 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 MAX6970 supply and the LEDs’ supply can power up in any order. The constant-current outputs are programmed together up to 55mA using a single external resistor. The MAX6970 operates with a 25Mbps, industry-standard, 4-wire serial interface.
The MAX6970 uses the industry-standard shift-registerplus-latch-type serial interface. The driver accepts data shifted into an 8-bit shift register using data input...
