AUTO-ECALL-REF, Automotive eCall Reference Design

Per contattare il Servizio Clienti.

• AUTO-ECALL-REF, Vehicles equipped with eCall systems will enable phone calls to an emergency service center in the event of an accident. Customers can accelerate the design of their eCall systems by taking advantage of a complete reference solution comprised of AEC-Q100 qualified integrated circuits (ICs). This reference design combines the TPA3111D1-Q1, highly efficient mono Class-D audio amplifier and the TPS43330-Q1, low Iq, single boost, dual synchronous buck controller with other analog and embedded processing components to create a robust, low cost solution that is scalable for other automotive applications such as telematics, stolen vehicle tracking and HEV/EV sound generation. It also incorporates the TPS7A1601-Q1 voltage regulator with low quiescent current and the MSP430F2232 16-bit ultra-low power microcontroller
