USB port protection for automotive infotainment and telematics
It clamps overvoltage events at 6V to protect the downstream USB transceiver and SoC, and carries AEC-Q100 qualification for deployment in under-hood and cabin-domain electronics. The device integrates ESD clamping and overvoltage protection in a single 10-VSSOP package, saving board area versus discrete TVS plus a separate OVP controller.
6V clamping — what it protects
The 6V clamping voltage is the key parametric: it keeps the USB data and VBUS lines below the absolute-maximum rating of most 5V-tolerant automotive USB PHYs and transceivers. If a short to a 12V or 24V automotive battery rail occurs on the USB connector, the TPD2S703QDGSRQ1 shunts the excess voltage before it reaches the controller. This is the spec that determines whether the infotainment head unit survives a miswired cable or a fault in the vehicle harness.
Automotive-grade assurance
The series designation is Automotive, AEC-Q100 — not a commercial or industrial grade. For a Tier-1 or OEM BOM that requires AEC-Q traceability at the component level, this part satisfies that requirement without a separate PPAP submission for the device itself.
