Overview

MAX6977 19-3554; Rev 2; 7/05 8-Port, 5.
5V Constant-Current LED Driver with LED Fault Detection General Description The MAX6977 serial-interfaced LED driver provides eight open-drain, constant-current sinking LED driver outputs rated at 5.
5V.
The MAX6977 operates from a 3V to 5.
5V supply.
The MAX6977 supply and the LEDs’ supply may power up in any order.
The constant-current outputs are programmed together to up to 55mA using a single external resistor.
The MAX6977 operates with a 25Mb, industry-standard, 4-wire serial interface.
The MAX6977 includes circuitry that automatically detects open-circuit LEDs.
Fault status is loaded into the serial interface shift register when LE goes high, an...
