Texas Instruments LM5158Q | Demoboard TIDA-020060
Automotive power over data lines PD reference design for 100/1000Base-T1 Ethernet applications
Overview
| Topology | Buck Converter |
| Input voltage | 15-60 V |
| Output 1 | 83 V |
| IC revision | FEBRUARY 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 Ethernet
- Footprint compatible to our 100Base-T1 SPE PHY
- Power sourcing equipment to supply up to 50W power via SPE cable
- Automotive qualified filter network for power coupling and decoupling
- Protection of the powered device with a high-side switch
- Implementation 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
