Description

This reference design implements power and driver notification functions typically found in an automotive instrument cluster. The design features reverse battery protection, a pre-boost stage to support cold-crank battery voltage conditions down to 3.5 volts, buck regulators for 3.3-V and 5-V supplies, an audio amplifier circuit to provide notifications, an LED backlight supply with automated brightness control and LED drivers with flexible diagnostic functions for tell-tale LEDs.

Features
  • Wide Vin range supports cold cranking to 3.5V and load dump to 40V
  • Tell-tale LED drivers with configurable fault diagnostics
  • 5V, single rail audio amplifier for chime and warning
  • Adjustable ambient backlight brightness with light sensor
  • Low loss reverse battery protection for reduced power dissipation
