Automotive power over data lines PD reference design for 100/1000Base-T1 Ethernet applications

Overview

TopologyBuck Converter
Input voltage15-60 V
Output 183 V
IC revisionFEBRUARY 2024

Description

This reference design demonstrates an implementation of Power over Data Lines (PoDL) for automotive use cases. The design uses a DP83TG720S-Q1 1000MBit/s single-pair Ethernet (SPE) PHY with the option to switch to the DP83TC812S-Q1 SPE PHY for 100MBit/s operation. A coupling and decoupling network is used to couple in a maximum power of 50W.

Features

Capable of 1000Base-T1 automotive EthernetFootprint compatible to our 100Base-T1 SPE PHYPower sourcing equipment to supply up to 50W power via SPE cableAutomotive qualified filter network for power coupling and decouplingProtection of the powered device with a high-side switchImplementation of PoDL according to the automotive market requirements by reducing cost and complexity of the implementation

Typical applications

  • Mechanincally scanning LIDAR
  • Rear camera
  • ADAS
  • Long range Ragdar
  • Radar ECU
