Texas Instruments TPS629210-Q1 | Demoboard TIDA-020061
Automotive power over data lines PD reference design for 100/1000Base-T1 Ethernet applications
Overview
| Topology | Buck Converter |
| Input voltage | 3-17 V |
| Output 1 | 55 V / 1 A |
| IC revision | FEBRUARY 2024 |
Description
This reference design implements a powered device (PD) to demonstrate Power over Data Lines (PoDL) in automotive applications. 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 split the data and power on the single-pair ethernet (SPE) cable.
Features
- Capable of 1000Base-T1 automotive Ethernet
- Footprint compatible to our 100Base-T1 SPE PHY
- This design features the implementation of the powered device to be powered via the single-pair ethernet cable
- Automotive qualified filter network for power coupling and decoupling with reverse polarity protection
- Implementation of PoDL according to the automotive market requirements by reducing cost and complexity of the implementation
Typical applications
- ADAS
- Rear camera
- Long range Ragdar
- Mechanincally scanning LIDAR
- Radar ECU
