Product details
Overview
TPD13S523PWR from Texas Instruments is a 13-channel HDMI ESD protection IC with integrated 5-V current-limited load switch, designed for HDMI 1.4 transmitter ports. It delivers ±12-kV IEC 61000-4-2 contact ESD protection, <0.05-pF differential capacitance matching across TMDS pairs, and 55-mA regulated 5V_OUT output with reverse-current blocking - enabling robust hot-plug detection in set-top boxes and tablets.
For engineers reviewing the TPD13S523PWR datasheet, TPD13S523PWR pinout, TPD13S523PWR application, or TPD13S523PWR equivalent, key selection criteria include its flow-through TSSOP-16 pin mapping for HDMI connector lines, ultra-low dynamic resistance (0.5 Ω typical) on TMDS clamps, support for >3.4 Gbps data rates, and dual-package availability (TSSOP/PW and UQFN/RSV) with identical functional pinout across variants.
Technical Context
The TPD13S523PWR integrates 8 high-speed TMDS ESD clamps (D0± to D3±), 5 control-line clamps (CTRL1–CTRL5 for CEC/HPD/UTILITY/SDA/SCL), and a monolithic 5-V load switch with 55-mA current limit and reverse-current blocking. All clamps share matched diode characteristics (<0.05-pF differential capacitance variation) to preserve HDMI signal integrity.
Its architecture uses low-RDYN (0.5 Ω typical) TVS diodes referenced to internal ground, with clamp voltages of 13 V (1-A surge) and 15 V (3-A surge), while the load switch maintains VOUT drop ≤205 mV at 55 mA and exhibits <0.69 µA reverse leakage when 5V_SUPPLY is unpowered.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD13S523RSVR | Identical electrical specs and pinout; uses 2.60 mm × 1.80 mm UQFN-16 package instead of TSSOP-16 | Better suited for space-constrained designs (e.g., smartphones) where PCB area is premium | Select RSVR for miniaturized layouts; PW (TPD13S523PWR) preferred for ease of routing and thermal management |
| TPD12S521DBTR | 12-channel HDMI protector (no UTILITY line support); lacks integrated 5V_OUT load switch - requires external regulator | Applicable only to HDMI 1.3 or legacy interfaces without UTILITY or strict 5V_OUT current-limiting requirements | Choose TPD12S521DBTR only if UTILITY line is unused and external 5-V regulation is already present |
Compared with TPD13S523RSVR, the TPD13S523PWR offers superior thermal dissipation (RθJA = 119.9°C/W vs. 153.2°C/W) and easier manual inspection, while TPD12S521DBTR requires additional components to meet HDMI 1.4 5V_OUT specifications - making TPD13S523PWR the optimal choice for full-spec, production-ready HDMI 1.4 transmitter protection.

FAQ
What is the primary function of the TPD13S523PWR in an HDMI system?
The TPD13S523PWR serves as a complete 13-channel ESD protection solution for HDMI 1.4 transmitter ports, integrating TVS clamps for all TMDS (D0±–D3±) and control lines (CTRL1–CTRL5), plus a current-limited 5V_OUT load switch. Its core function is to absorb ±12-kV IEC 61000-4-2 ESD strikes while delivering compliant 5-V power to downstream receivers - all within a single TSSOP-16 package. The TPD13S523PWR achieves this without signal degradation thanks to <0.05-pF differential capacitance matching and 0.5-Ω dynamic resistance on TMDS paths.
Does the TPD13S523PWR require external components to meet HDMI 1.4 specifications?
No, the TPD13S523PWR is designed as a drop-in solution requiring only two external 0.1-µF decoupling capacitors - one on 5V_SUPPLY and one on 5V_OUT - to meet HDMI 1.4 electrical requirements. It integrates all 13 ESD clamps and the 55-mA current-limited 5V_OUT regulator internally, eliminating the need for discrete TVS diodes, external FETs, current-sense resistors, or reverse-blocking diodes. The TPD13S523PWR's flow-through pinout further removes routing complexity by aligning directly with standard HDMI connector pinouts.
How does the TPD13S523PWR handle reverse current flow from connected HDMI devices?
The TPD13S523PWR incorporates built-in reverse-current blocking in its integrated 5V_OUT load switch, limiting backfeed leakage to ≤0.69 µA when 5V_SUPPLY is unpowered and 5V_OUT is pulled to 5 V. This feature prevents unintended power-up of the source-side HDMI transmitter when two devices are inadvertently connected back-to-back - a known risk in docking station and multi-display configurations. The TPD13S523PWR achieves this through internal MOSFET control logic that disables conduction from 5V_OUT to 5V_SUPPLY under reverse-bias conditions.
What is the maximum data rate supported by the TPD13S523PWR on TMDS lines?
The TPD13S523PWR supports HDMI data rates in excess of 3.4 Gbps - the maximum defined for HDMI 1.4 - enabled by its ultra-low 1-pF pin capacitance and <0.05-pF differential capacitance matching between TMDS pairs. Eye diagram testing confirms no measurable degradation at 1080p resolution with a 340-MHz pixel clock and 3.4-Gbps aggregate rate. The TPD13S523PWR's 0.5-Ω dynamic resistance also ensures fast clamping response (<10 ns) during ESD transients without distorting high-frequency signal edges.
Can the CTRLx pins on the TPD13S523PWR be used interchangeably for different HDMI control signals?
Yes, all five CTRLx pins (CTRL1–CTRL5) on the TPD13S523PWR are functionally identical and fully interchangeable - each provides the same ESD clamp structure for HDMI control lines including CEC, HPD, UTILITY, SDA, and SCL. The datasheet explicitly states "all the CTRLx pins have the same ESD circuit and are interchangeable," allowing designers to assign them flexibly based on PCB routing needs without affecting protection performance. This uniformity simplifies layout and eliminates signal-specific pin dependencies in the TPD13S523PWR design.
