Description

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
