A8519-1 Datasheet Fault-tolerant Led Driver

Manufacturer: Allegro MicroSystems

Overview: A8519 and A8519-1 Wide Input Voltage Range, High-Efficiency, Fault-Tolerant LED.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The A8519 is a multi-output LED driver for small-size LCD backlighting.

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

The boost converter can drive up to 44 white LEDs, 11 LED per string, at 100 mA.

Key Features

  • Automotive AEC-Q100 qualified.
  • Fully integrated 42 V MOSFET for boost converter.
  • Fully integrated LED current sinks.
  • Withstands surge input up to 40 VIN for load dump.
  • Operates down to 3.9 VIN (max) for idle stop.
  • Drives four strings of LEDs.
  • Maximum output voltage 40 V.
  • Up to 11 white LEDs in series.
  • Drive current for each string is 100 mA.
  • Programmable boost switching frequency (200 kHz to 2.15 MHz).
