Texas Instruments LM5150-Q1 | Demoboard TIDA-01628

1.5-V to 42-V wide VIN, low IQ boost controller with 4 programmable output voltage options

Overview

TopologyOther Topology
IC revisionB

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
