TPD3S713AQRVCRQ1 - 18V USB2.0 Surge Protection IC | TI

The Texas Instruments TPD3S713AQRVCRQ1 is an automotive-grade USB 2.0 interface protection IC integrating an 18V-rated internal switch with 0.05-A to 0.6-A adjustable current limit and VBUS/D+/D- short-to-VBATT protection, housed in a 20-pin WQFN (RVC, 4x3 mm) package rated from -40C to +125C. It is part of the TPD3S713A-Q1 family qualified to AEC-Q100 for automotive deployment. USB interface protection ICs are a class of circuit-protection devices that guard downstream transceivers and system circuits against overvoltage, surge, and short-to-battery faults on USB cable connections. Within the power-protection hierarchy, they sit between surge suppressors and hot-swap/eLoad switches, combining an ESD-rated front end, an internal FET switch, and fault-detection logic in a single surface-mount device. Key features include overvoltage tolerance up to 18 V DC on the VBUS, DP_IN, and DM_IN pins for both hot-plug and DC events, an adjustable current limit covering the 0.05-A to 0.6-A USB 2.0 load range, and automatic switch shutdown that isolates the upstream transceiver from harmful voltage and current spikes. Integrated ESD protection on the line pins reduces external component count. Technically, the TPD3S713x-Q1 monitors VBUS, DP_IN, and DM_IN continuously; when a fault such as a short to the vehicle battery (VBATT) is detected on any of these lines, the internal switches open within microseconds to protect the connected USB transceiver. The A-version offers the extended adjustable current-limit range for designs requiring precise inrush and load control. Typical applications include automotive USB charging and data ports, infotainment head units, telematics control units, and USB 2.0 hub ports exposed to the harsh electrical environment of a 12-V vehicle battery system. When designing with this device, verify that the adjustable current-limit setting, programmed via the ILIM pin, accommodates worst-case USB load transients without nuisance tripping, and observe datasheet PCB layout guidance for thermal performance.
