Product details
Overview
TPD2S703QDSKRQ1 from Texas Instruments is an AEC-Q100 qualified automotive USB 2-channel short-to-battery and IEC 61000-4-2 ESD protection IC. It integrates dual nFET data switches with ±8-kV contact/±15-kV air-gap ESD protection on VD+/VD−, 18-V short-to-battery tolerance, 200-ns overvoltage response, and adjustable OVP threshold via resistor divider. It enables robust USB 2.0 interface protection in head units and telematics modules.
For engineers reviewing the TPD2S703QDSKRQ1 datasheet, TPD2S703QDSKRQ1 pinout, TPD2S703QDSKRQ1 application, or TPD2S703QDSKRQ1 equivalent, key selection criteria include its dual-channel short-to-battery isolation performance, flow-through routing for signal integrity, thermal shutdown behavior, FLT fault signaling, and compatibility with 5-V-only power architecture in automotive infotainment systems.
Technical Context
The TPD2S703QDSKRQ1 implements two independent high-speed nFET switches between VD+/D+ and VD−/D−, each with 4–6.5 Ω on-resistance and 960-MHz bandwidth. Its overvoltage protection circuitry monitors VD+/VD− against a user-adjustable threshold (0.66 V to 3.8 V) and disables both switches within 1 µs upon detection of >18-V transients.
It operates in two modes: Mode 0 uses fixed 3.3-V VREF; Mode 1 enables programmable OVP via external RTOP/RBOT resistors on MODE/VREF pins. The integrated open-drain FLT pin asserts during overvoltage events and auto-resets after 32-ms recovery, while EN provides active-low enable control and thermal shutdown activates at 140–165°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection | ±8-kV contact / ±15-kV air-gap per IEC 61000-4-2 and ISO 10605 on VD+/VD− pins - eliminates need for external TVS diodes |
| Short-to-Battery Tolerance | Withstands 18-V DC shorts on VD+/VD− - protects against battery hot-plug events in automotive environments |
| OVP Response Time | ≤1 µs turnoff time for 18-V transients - limits energy transfer to downstream USB transceivers |
| Data Switch Bandwidth | 960 MHz (–3 dB) - preserves USB 2.0 signal integrity with minimal eye diagram degradation |
| Operating Temperature | –40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and cabin applications |
| Supply Voltage | 4.5 V to 7 V VPWR - supports standard 5-V rail without auxiliary supplies |
| Adjustable OVP Threshold | 0.66 V to 3.8 V via resistor divider on VREF/MODE - enables system-level optimization across transceiver voltage ranges |
Pinout & Package
TPD2S703QDSKRQ1 is packaged in a 10-pin WSON (2.5 mm × 2.5 mm) with wettable flanks, optimized for automated optical inspection and high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, VD− | High-voltage USB D− line input | Connects directly to USB connector; handles up to 18-V shorts and IEC ESD clamping |
| 2, VD+ | High-voltage USB D+ line input | Connector-side pin with identical protection specs as VD−; enables differential short-to-battery immunity |
| 3, GND | Power and ESD return path | Common reference for internal clamps, switches, and thermal pad; must be low-inductance connection |
| 4, FLT | Open-drain fault indicator | Asserts low during OVP/thermal events; requires external pull-up; auto-resets after 32 ms post-clearance |
| 5, EN | Active-low enable control | Drives switches ON/OFF; 150-µs turnon time; supports system-level power sequencing |
| 6, MODE | Mode selection and VREF reference | Configures Mode 0 (fixed) or Mode 1 (adjustable OVP); acts as LDO reference in Mode 1 |
| 7, VPWR | 5-V supply input | Powers internal logic, switches, and protection circuits; accepts 4.5–7 V with UVLO hysteresis |
| 8, VREF | OVP threshold setting node | Accepts resistor-divider voltage (0.63–3.8 V) to define rising OVP trip point with ±8% accuracy |
| 9, D+ | Protected low-voltage USB D+ output | Connects to upstream transceiver; clamped to ≤6 V during 18-V STB events |
| 10, D− | Protected low-voltage USB D− output | Matches D+ behavior; maintains differential signaling integrity under fault conditions |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through routing | Minimizes trace discontinuities and impedance mismatches - preserves USB 2.0 eye opening and jitter margin |
| Adjustable OVP threshold | Programmable 0.66–3.8 V trip point via external resistors - matches diverse transceiver I/O voltage requirements |
| Integrated FLT signaling | Dedicated open-drain fault pin with 32-ms recovery - enables host MCU to log faults and initiate diagnostics without polling |
| Thermal shutdown | 140–165°C activation with 10–15°C hysteresis - prevents latch-up during sustained overtemperature conditions |
| Single 5-V supply operation | Eliminates need for auxiliary rails - reduces BOM count and power tree complexity in space-constrained modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB data line protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB30DRYR | Single-channel, 5.5-V max OVP, no short-to-battery capability, smaller 1.6-mm² X2SON package | Targeted at consumer USB 3.0 ports; lacks AEC-Q100 qualification and 18-V STB rating | Select only for non-automotive, low-voltage USB 3.0 applications where space is critical and battery shorts are not a concern. |
| TPD4S012RSVR | 4-channel, fixed 3.6-V OVP, no adjustable threshold, supports USB 2.0/3.0 but no thermal shutdown | Designed for multi-port automotive hubs; higher channel count but less flexible OVP tuning than TPD2S703QDSKRQ1 | Choose when protecting ≥3 USB lines simultaneously and precise OVP threshold adjustment is unnecessary. |
Compared with TPD2EUSB30DRYR and TPD4S012RSVR, the TPD2S703QDSKRQ1 uniquely combines AEC-Q100 qualification, programmable 0.66–3.8-V OVP, 18-V short-to-battery tolerance, and integrated thermal shutdown - making it the only option for high-reliability, single-connector automotive USB 2.0 protection with system-level fault visibility.

FAQ
What is the maximum short-to-battery voltage the TPD2S703QDSKRQ1 can withstand?
The TPD2S703QDSKRQ1 withstands up to 18 V on its VD+ and VD− pins during short-to-battery events, as verified per AEC-Q100 test conditions. This rating ensures robust protection against accidental connection to vehicle battery rails during service or cable hot-plug operations, with clamping voltages limited to ≤6 V on the protected D+/D− outputs.
Does the TPD2S703QDSKRQ1 require more than one supply voltage?
No, the TPD2S703QDSKRQ1 operates from a single 5-V supply (VPWR), with a specified range of 4.5 V to 7 V. It does not require separate bias rails for protection circuitry or logic - simplifying power architecture in automotive modules where board space and BOM cost are constrained.
How does the FLT pin behave during and after an overvoltage event?
The FLT pin on the TPD2S703QDSKRQ1 asserts low within 12.6–23.4 ms of OVP detection and remains asserted until the overvoltage condition clears. After clearance, FLT deasserts automatically after a 32-ms recovery period, providing a clean, self-timed fault indication without requiring host MCU intervention or reset sequencing.
Can the overvoltage protection threshold of the TPD2S703QDSKRQ1 be adjusted?
Yes, the TPD2S703QDSKRQ1 supports adjustable OVP thresholds from 0.66 V to 3.8 V using an external resistor divider on the VREF and MODE pins. In Mode 1, the rising OVP threshold equals 1.19× to 1.31× the applied VREF voltage, enabling precise matching to various USB transceiver I/O voltage levels.
Is the TPD2S703QDSKRQ1 compatible with USB 3.0 data rates?
The TPD2S703QDSKRQ1 is specified for USB 2.0 (480 Mbps) with 960-MHz bandwidth and validated eye diagrams. While it passes USB 3.0 connector-level ESD tests, its 960-MHz –3-dB bandwidth is insufficient for SuperSpeed (5 Gbps) signal integrity - use only for USB 2.0 lanes in mixed-interface designs.
