TPD3S713AQRVCRQ1 - 18V USB2.0 Surge Protection IC | TI
MPN: TPD3S713AQRVCRQ1 ✓ Hoạt độngTPD3S713AQRVCRQ1 Tóm tắt
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.

Ứng dụng tiêu biểu
TPD3S713AQRVCRQ1 phù hợp cho 6 Áp dụngs: Automotive USB Charging Ports, Infotainment Head Units, Telematics Control Units, Automotive USB Hubs, On-Board Diagnostics and Service Ports, Industrial USB 2.0 Equipment.
Automotive USB Charging Ports
The TPD3S713AQRVCRQ1 is purpose-built for automotive USB charging ports, where the VBUS line can be exposed to battery shorts, hot-plug transients, and load-dump events. Its 18 V overvoltage tolerance on VBUS covers DC and transient faults on a 12 V vehicle rail, while the 0.05-A to 0.6-A adjustable current limit lets designers program port current for standard or dedicated charging profiles. The internal switch isolates the downstream system within the datasheet response time, and AEC-Q100 qualification with -40C to +125C operation guarantees behavior across the full automotive environment. Placed directly behind the USB connector, it eliminates separate TVS and switch stages, saving board area in space-constrained center-console designs.

Infotainment Head Units
Automotive infotainment head units expose USB 2.0 data lines (D+/D-) to consumer cable abuse, including shorts to the vehicle battery when connectors are damaged. The TPD3S713AQRVCRQ1 protects DP_IN and DM_IN in addition to VBUS, shutting off the internal switches to isolate the upstream USB transceiver from harmful voltage and current spikes per the TI datasheet. This line-level protection distinguishes it from VBUS-only switches, which leave the transceiver exposed. With integrated 18 V tolerance on all three protected lines and AEC-Q100 qualification from -40C to +125C, a single 4x3 mm WQFN replaces multiple discrete components, simplifying layout near the connector and improving fault robustness for the head unit's SoC USB PHY.
Được đề xuất
Telematics Control Units
Telematics control units (TCUs) use USB 2.0 interfaces for diagnostics, firmware update, and cellular-module connectivity, operating in the harshest electrical zone of the vehicle near antenna and battery wiring. The TPD3S713AQRVCRQ1's short-to-VBATT protection on VBUS, DP_IN, and DM_IN guards the TCU's transceiver when a service cable is miswired or damaged, events that occur during fleet maintenance. The adjustable 0.05-A to 0.6-A current limit protects the often current-constrained always-on supply rail feeding the TCU, while the 18 V overvoltage tolerance handles jump-start and transient conditions. AEC-Q100 qualification and the compact 20-pin WQFN (RVC) package suit the high-density, thermally constrained PCBs typical of TCUs.

Automotive USB Hubs
Rear-seat and center-console USB hubs distribute 5 V and USB 2.0 data to multiple passenger ports, multiplying exposure to faults because any one damaged cable or connector can short a live line to the vehicle battery. The TPD3S713AQRVCRQ1 placed at each hub port provides per-port 18 V overvoltage clamping and adjustable current limiting from 0.05 A to 0.6 A, so a single faulty port does not drag down the shared upstream rail or damage the hub controller. Automatic switch shutdown isolates VBUS, DP_IN, and DM_IN within the datasheet response time, preserving service on the remaining ports. Its 4x3 mm WQFN footprint allows dense multi-port layouts with consistent protection characteristics across all channels.

On-Board Diagnostics and Service Ports
Vehicle diagnostic and service USB ports are frequently mated and unmated by technicians, making them statistically the most fault-prone USB interfaces in the car. The TPD3S713AQRVCRQ1 protects against the classic field failure of a bent or contaminated connector shorting VBUS or the data lines to VBATT: the IC senses the overvoltage up to 18 V DC and opens the internal switches to isolate the upstream transceiver, per the TI datasheet. The 0.05-A to 0.6-A adjustable current limit also limits current drawn by a partially shorted cable, preventing connector heating. Its -40C to +125C AEC-Q100 rating covers under-hood-adjacent and trunk-mounted OBD module environments without derating.

Industrial USB 2.0 Equipment
Although automotive-qualified, the TPD3S713AQRVCRQ1's 18 V overvoltage tolerance and short-to-battery-style line isolation transfer directly to industrial USB 2.0 ports on PLCs, HMIs, and test instruments, where 24 V wiring mistakes can reach a USB connector. The device's adjustable 0.05-A to 0.6-A current limit protects the internal 5 V supply from downstream faults, while its -40C to +125C operating range covers unconditioned industrial cabinets. Note that the 18 V maximum overvoltage rating is below a full 24 V bus exposure, so series impedance or front-end clamping is recommended for ports that could contact a 24 V industrial rail. The single-chip integration still reduces component count versus discrete TVS plus switch designs.

Ghi chú thiết kế
The 18 V overvoltage rating applies to the VBUS, DP_IN, and DM_IN pins only. Verify that no system node subject to full 24 V industrial rail or automotive load-dump above 18 V can connect directly to these pins; otherwise add upstream series impedance or front-end clamping. Also program the ILIM pin resistor so the 0.05-A to 0.6-A limit accommodates USB inrush capacitance without nuisance trips - consult the TI TPD3S713-Q1/TPD3S713A-Q1 datasheet (Rev. B) ILIM setting table for resistor selection.
Place the TPD3S713AQRVCRQ1 as close to the USB connector as possible so protected traces are short and the exposed D+/D- runs downstream of the IC are minimized. Follow the datasheet layout section: solid ground plane under the WQFN center pad for thermal dissipation and low-impedance return, and symmetric routing of DP/DM pairs to preserve USB 2.0 90-ohm differential impedance. Use the RVC package recommended land pattern from the TI datasheet for reliable reflow.
Estimated: with the internal switch conducting a continuous 0.6 A limit, power dissipation equals I^2 x Rds(on) of the internal FET. Because the exact Rds(on) value was not present in the retrieved data, calculate junction rise using the datasheet Rds(on) and the RVC package theta-JA, and ensure a PCB copper pour of adequate area per TI layout guidance. Recheck at maximum ambient of +125C to keep the junction below the datasheet maximum rating.
