Design files

Overview

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
