Class-D audio amplifier designed for eCall, instrument cluster and telematics
Texas Instruments (Dallas, TX) introduced the industry’s first automotive Class-D audio amplifier to integrate load-dump protection and diagnostics in a single device for emergency call (eCall) and instrument cluster systems. Designers can eliminate multiple discrete components, simplify automotive-grade diagnostic design and extend battery back-up power with the mono-channel, analog differential input TAS5421-Q1. Features include:
- 40-V load dump and over-temperature to protect against harsh automotive conditions.
- High efficiency and low quiescent current.
- Integrated I2C diagnostics.
