Overview

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.

Key Features

dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for output regulation. The ISL97677 can operate in multiple modes of operations. It can be controlled by SMBus/I2C communications.
