E-Mobility’s Shift to a More Efficient Future (Download)

Power over data line (PoDL) and single-pair Ethernet (SPE) represent the next steps in the automotive shift toward data-centric electric vehicles. As modern cars incorporate an increasing number of data-centric sensors and subsystems, they now generate more data than traditional designs can efficiently handle. At the same time, automakers are under pressure to reduce weight whenever possible to minimize costs.

PoDL, when paired with SPE, is an emerging technology designed to address both challenges. This article discusses the developments leading to SPE and PoDL, as well as the protection elements implemented to protect against overvoltage and overcurrent events.
