Automotive Off-Battery Processor Power Reference Design for ADAS and Infotainment

TIDA-00805

Design files

Overview

The TIDA-00805 reference design is an off-battery automotive power solution targeting processors in advanced driver assistance systems (ADAS) like surround view, front camera and driver monitoring, as well as infotainment systems such as cluster and head unit. The design operates directly from a 3.9 to 40V car battery input and provides all supply rails for the application processor, Controller Area Network (CAN), input/output interfaces and double data rate (DDR) memory.

Features
  • Supports power and sequencing requirements of modern processors
  • Small solution size
  • Provides all power supply rails for TDA2x/TDA2Ex and DRA72x/DRA74x/DRA75x application processors
  • Supports start-stop, cold and warm cranking down to 3.9 V
  • Supports peripheral supplies (I/Os, memory)
