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.

Features
♦ 25Mbps Industry-Standard 4-Wire Serial Interface at 5V
♦ 3V to 5.5V Logic Supply
♦ Eight Constant-Current LED Outputs Rated at 36V
♦ Up to 55mA Continuous Current per Output
♦ Output Current Programmed by Single Resistor
♦ 3% Current Matching Between Outputs
♦ 6% Current Matching Between ICs
♦ -40°C to +125°C Temperature Range

Applications
   Variable Message Signs
   Marquee Displays
   Point-of-Order Signs
   Traffic Signs
   Gaming Features
   Architectural Lighting
