A8522 - Multi-Channel LED Driver

General Description

The A8522 is a programmable multi-output LED driver for LCD backlighting.

It integrates a current-mode boost converter with internal power switch and 8 current sinks.

The IC operates from 4.5 to 36 V, and is able to withstand up to 40 V load-dump conditions encountered in automotive systems.

Key Features

  • AEC-Q100 qualified.
  • Wide input voltage range of 4.5 to 36 V.
  • Operates down to 3.9 V (VIN falling) for idle stop, and up to 40 V for load dump.
  • Integrated boost converter with DMOS switch and OVP protection up to 39 V.
  • 8 fully integrated LED current sinks, with individually programmable current up to 60 mA per channel.
  • I2C™ interface for programming LED current, PWM dimming, and various protection thresholds per channel.
  • Ability to d.
