Texas Instruments TPD3S713QRVCRQ1

Overview

TPD3S713QRVCRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive USB 2.0 interface protection IC integrating high-bandwidth data switches (1230 MHz), short-to-battery protection up to 18 V on VBUS/DP_IN/DM_IN, ±8-kV IEC 61000-4-2 ESD rating, and adjustable 50–600 mA current-limited load switch - deployed in head units and telematics modules for robust in-vehicle USB connectivity.

For engineers reviewing the TPD3S713QRVCRQ1 datasheet, TPD3S713QRVCRQ1 pinout, TPD3S713QRVCRQ1 application, or TPD3S713QRVCRQ1 equivalent, key selection criteria include its 1.23 GHz analog switch bandwidth, dual overvoltage protection thresholds (6.0 V on VBUS, 3.9 V on DP/DM), integrated IMON current monitoring, thermal shutdown at 155°C, and WQFN-20 (3 mm × 4 mm) package with exposed thermal pad.

Technical Context

The TPD3S713QRVCRQ1 implements a dual-path protection architecture: a high-side MOSFET (73 mΩ typical rDS(on)) with programmable current limiting via external ILIM_HI/ILIM_LO resistors, and independent high-speed analog switches for DP/DM lines featuring <10.9 pF on-state capacitance and 34 dB cross-channel isolation at 250 MHz. Its fault response includes deglitched FAULT assertion (11–23 ms for OVP, 5.5–11.5 ms for overcurrent) and automatic recovery after overvoltage removal.

It supports two operational modes-normal mode (INT1 = high) and client mode (INT1 = low + ILIM_SEL = low)-enabling flexible integration with upstream USB host controllers. Cable compensation (CS pin) sinks 190–230 µA to dynamically adjust upstream DC-DC output voltage and maintain stable 5 V at remote ports across long automotive cables.

FAQ

What is the maximum short-to-battery voltage the TPD3S713QRVCRQ1 can withstand on its DP_IN and DM_IN pins?

The TPD3S713QRVCRQ1 withstands up to 18 V short-to-battery events on both DP_IN and DM_IN pins, triggering immediate shutdown of the internal data switches and asserting the FAULT pin with a 16-ms deglitch. This protection is specified across the full –40°C to +125°C operating temperature range and ensures upstream USB transceivers remain undamaged during battery fault exposure in automotive environments. The TPD3S713QRVCRQ1 maintains this rating without latch-off behavior, enabling automatic recovery once the overvoltage condition is removed.

How does the TPD3S713QRVCRQ1 implement cable compensation, and what design impact does it have?

The TPD3S713QRVCRQ1 implements cable compensation via its CS pin, which sinks a precise 190–230 µA current (at 0.5 A load) to control the feedback node of an upstream DC-DC converter. This dynamically adjusts the converter's output voltage to offset IR drop across long USB cables-ensuring ≥4.75 V is maintained at the remote port even under full 500 mA load. The TPD3S713QRVCRQ1's CS function eliminates voltage droop-induced USB enumeration failures and supports stable BC1.2 charging negotiation in automotive media interfaces.

Can the TPD3S713QRVCRQ1 be used in USB client mode, and how is it configured?

Yes, the TPD3S713QRVCRQ1 supports client mode operation when INT1 is pulled low and ILIM_SEL is also held low. In this mode, the device disables certain internal protections to align with USB peripheral-side timing and signaling requirements-such as relaxed OVP response on DP_IN/DM_IN. Client mode is validated for use with automotive USB peripherals like rear-seat cameras or microphones, and the TPD3S713QRVCRQ1 retains full short-to-battery and ESD protection regardless of mode. Configuration requires no external components beyond standard pull-down resistors.

What is the thermal performance of the TPD3S713QRVCRQ1 in a typical automotive PCB layout?

The TPD3S713QRVCRQ1 in its 20-pin WQFN package achieves a junction-to-board thermal resistance (RθJB) of 11.9°C/W when mounted on a 4-layer PCB with 1-in² 2-oz copper thermal pad connected to the exposed die paddle. At 500 mA continuous load and 40°C ambient, junction temperature rise remains below 60°C-well within the 125°C max operating limit. The TPD3S713QRVCRQ1 also features thermal shutdown at 155°C (with 20°C hysteresis) to prevent permanent damage during sustained overload or poor heatsinking conditions.

Does the TPD3S713QRVCRQ1 provide diagnostic capability for system-level fault analysis?

Yes, the TPD3S713QRVCRQ1 provides three integrated diagnostic functions: (1) FAULT pin asserts low during overtemperature, overcurrent, or overvoltage events with mode-specific deglitch timing; (2) IMON pin sources a 265 µA/A proportional current for real-time load monitoring; and (3) separate INT1/ILIM_SEL pins allow software-configurable mode selection and current threshold switching. These features enable comprehensive fault logging, dynamic power budgeting, and adaptive protection tuning-all without external ADCs or comparators-making the TPD3S713QRVCRQ1 suitable for ASIL-B–aligned automotive diagnostics.
