Automotive Emergency Call (eCall) Audio Subsystem Reference Design
Description
The efficiency and diagnostics necessary for automotive emergency call (eCall) systems generate unique requirements for the audio subsystem, such as speaker diagnostics, and low power consumption. This TI Design shows how to use TI's automotive two-channel audio codec (TLV320AIC3104-Q1) and a class-D audio amplifier (TAS5411-Q1) for eCall applications.
Features
- The integrated load-dump protection reduces external voltage clamp cost and size
- Onboard load diagnostics report the status of the speaker through I2C, which reduces external components needed for diagnostic coverage
- TLV320AIC3104-Q1 + TAS5411-Q1 combo allows for reduced power consumption, reduced heat and reduced peak currents in the electrical system
- TAS5411-Q1 provides up to 8W output power for loud, clear audio in an unpredictable emergency environment
- Additional output from the TLV320AIC3104-Q1 can be used for the head unit or other car audio needs and eliminates the need for another device
Applications
- Telematics Control Unit
