Texas Instruments LM5158Q | Demoboard TIDA-020060
Automotive power over data lines PD reference design for 100/1000Base-T1 Ethernet applications
Details
| Topologie | Abwärtswandler |
| Eingangsspannung | 15-60 V |
| Ausgang 1 | 83 V |
Beschreibung
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.
Eigenschaften
- 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
Typische Anwendungen
- Radar ECU, Long range Ragdar, ADAS, Mechanincally scanning LIDAR, Rear camera
