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
| Topology | Other Topology |
| IC revision | B |
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
