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

Typical applications

• Hybrid Cluster with Active Graphics Support, Hybrid Cluster with Informational Graphics Support, Reconfigurable Digital Cluster
