Automotive Power Reference Design for Low Power TDA3x Based Systems

TIDA-00530

Design files

Overview

This solution was designed to make an integrated, size-optimized power design for ADAS applications using the TDA3x SoC off of an automotive battery input.  By targeting only applications with lower processing needs, we’re able to choose devices and components which are smaller, compared to systems utilizing higher performance processors.

Features
  • Complete TDA3x, DDRx, and CAN power solution
  • Highly-integrated, size-optimized design
  • Off-Battery operation
  • Full power up/down sequencing
  • Designed to meet ISO 7637-2:2004

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
