ISL97677 SMBus/I2C 8-Channel LED Driver OBSOLETE PRODUCT NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc DATASHEET FN6996 Rev.2.00 Sep 13, 2017 The ISL97677 is an SMBus/I2C controlled multichannel LED driver for notebook and monitor LCD backlight applications with PWM dimming and fault reporting functions. The ISL97677 is capable of driving typically 96 pieces of 3.4V/50mA LEDs. The ISL97677 has multiple channels of voltage controlled current sources with typical currents matching to ±0.7%, which compensate for the non-uniformity effect of forward voltages variance in the LED strings.
