Product details
Overview
TPD13S523RSVR from Texas Instruments is a 13-channel HDMI 1.4/1.3 ESD protection IC with integrated 5-V current-limited load switch, ±12-kV IEC 61000-4-2 contact ESD rating, <0.05-pF differential capacitance between TMDS pairs, and 55-mA output current capability at 5V_OUT. It protects HDMI transmitter ports in set-top boxes and tablets.
For engineers reviewing the TPD13S523RSVR datasheet, TPD13S523RSVR pinout, TPD13S523RSVR application, or TPD13S523RSVR equivalent, key selection criteria include differential capacitance matching for 3.4-Gbps TMDS integrity, reverse-current blocking compliance with HDMI 5-V spec, and UQFN (RSV) package footprint for space-constrained layouts.
Technical Context
The TPD13S523RSVR integrates monolithic TVS clamps across all 13 HDMI signal paths - eight TMDS differential pairs (D0± to D3±) and five control lines (CTRL1–CTRL5) - with matched dynamic resistance (RDYN = 0.5 Ω typ) and sub-1-pF individual pin capacitance. Its on-chip load switch regulates 5V_OUT with 205-mV dropout at 55 mA and blocks reverse current when 5V_SUPPLY is unpowered.
ESD protection operates via bidirectional clamping diodes triggered above VBR (6 V) or below VF (0.85 V), diverting ±12-kV contact strikes to GND within nanoseconds. The device requires no external components for full HDMI port protection and supports operation from –40°C to 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±12-kV contact discharge on all connector-facing pins - meets Level 4 system-level ESD immunity without external TVS arrays. |
| TMDS Differential Capacitance Matching | <0.05 pF mismatch between Dx+ and Dx− pairs - preserves signal integrity and eye opening at 3.4 Gbps HDMI data rates. |
| Load Switch Output Current | 55 mA at 5V_OUT - supplies sufficient current for HDMI receiver hot-plug detection even when sink device is powered off. |
| Dynamic Resistance (RDYN) | 0.5 Ω typical - ensures low clamping voltage (13 V @ 1 A, 15 V @ 3 A) during ESD transients, minimizing stress on upstream transmitter. |
| Supply Voltage Range | 4.5 V to 5.5 V on 5V_SUPPLY - compatible with standard 5-V rail tolerances and supports VDROP of 205 mV at full load. |
| Operating Temperature | –40°C to 85°C - qualified for industrial and consumer embedded applications including STBs and portable displays. |
| Package | 16-pin UQFN (RSV), 2.6 mm × 1.8 mm - enables high-density routing near HDMI connectors with minimal PCB area. |
Pinout & Package
TPD13S523RSVR uses a 16-pin UQFN (RSV) package with wettable flanks, 0.4-mm pitch, and exposed thermal pad. Pin 1 is marked by a dot; orientation follows quadrant Q1 per tape-and-reel standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CTRL1–CTRL5 | ESD clamp I/O | Interchangeable protection for CEC, HPD, SCL/SDA, and UTILITY lines - identical clamping characteristics across all five pins. |
| 5V_SUPPLY | Input supply | Connects to system 5-V rail; powers internal load switch and ESD clamps - requires 0.1–1-µF bypass capacitor to GND. |
| 5V_OUT | Regulated output | Current-limited 5-V output for HDMI receiver power; provides reverse-current blocking and short-circuit protection up to 147 mA. |
| GND | Ground reference | Common return for ESD current discharge and load switch operation - must connect to solid ground plane with low-inductance path. |
| D0+ to D3+ | TMDS positive clamp | High-speed ESD protection for TMDS data lanes - optimized for <1-pF capacitance and matched impedance to preserve differential signaling. |
| D0– to D3– | TMDS negative clamp | Complementary negative-side clamps paired with D0+–D3+ - maintains <0.05-pF differential capacitance tolerance for signal fidelity. |
Key Features
| Feature | Design Value |
|---|---|
| Single-chip HDMI port protection | Replaces discrete TVS arrays and external load switches - eliminates 13+ passive components while ensuring pin-to-pin flow-through mapping. |
| Ultra-low differential capacitance mismatch | <0.05 pF variation between TMDS+ and TMDS− clamps - prevents skew-induced jitter and maintains HDMI 1.4 eye diagram compliance. |
| Integrated 5-V load switch with reverse blocking | Enables HDMI hot-plug detection and prevents backfeeding from downstream receivers - satisfies HDMI specification Section 5.2.2.2. |
| Flow-through pinout for TMDS lanes | Direct Dx+ and Dx− routing through package - minimizes trace length and stubs, reducing insertion loss and crosstalk in high-speed layouts. |
| Interchangeable CTRLx pins | All five control-line clamps share identical electrical specs - simplifies layout and allows flexible assignment of CEC, HPD, UTILITY, SCL, and SDA. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD12S016RGER | 12-channel HDMI ESD protector (no integrated load switch); 0.8-pF max pin capacitance; supports up to 2.25 Gbps. | Lacks 5-VOUT current-limiting and reverse-blocking - requires external LDO and diode for HDMI 5-V compliance. | Select when cost sensitivity outweighs integration needs and data rate ≤2.25 Gbps suffices. |
| SZP13S523RSVR | Automotive-grade variant (AEC-Q100 Grade 2); identical pinout, specs, and RSV package - differs only in qualification and marking. | Qualified for –40°C to 105°C operation and automotive EMC environments - not intended for consumer temperature ranges. | Choose for infotainment systems requiring automotive qualification; otherwise, TPD13S523RSVR is optimal for commercial use. |
Compared with TPD12S016RGER, TPD13S523RSVR delivers full HDMI 1.4 integration with 3.4-Gbps support and eliminates external power components; versus SZP13S523RSVR, it offers lower cost and qualification overhead for non-automotive designs without sacrificing performance or footprint.

FAQ
What is the maximum HDMI data rate supported by the TPD13S523RSVR?
The TPD13S523RSVR supports data rates in excess of 3.4 Gbps, fully compliant with HDMI 1.4 specifications. This capability is enabled by its <0.05-pF differential capacitance matching between TMDS pairs and low RDYN (0.5 Ω) clamping, which preserve signal integrity and eye opening at high frequencies. Measured eye diagrams confirm clean waveform fidelity at 3.4 Gbps with 1080p resolution.
Does the TPD13S523RSVR require external components for basic HDMI protection?
No, the TPD13S523RSVR is a single-chip solution requiring only two external 0.1-µF capacitors - one on 5V_SUPPLY and one on 5V_OUT - for proper operation. All 13 HDMI signal lines (eight TMDS and five control) are protected internally, and the integrated load switch eliminates the need for external regulators or reverse-blocking diodes. No additional TVS diodes or current-limiting resistors are needed.
How does the TPD13S523RSVR handle reverse current flow from an HDMI sink device?
The TPD13S523RSVR incorporates reverse-current blocking in its integrated load switch, limiting IBACKDRIVE to just 0.69 µA (typ) when 5V_SUPPLY is unpowered and 5V_OUT is pulled to 5 V. This feature prevents erroneous turn-on of the HDMI transmitter side when two sources are inadvertently connected and ensures strict compliance with HDMI specification Section 5.2.2.2 for 5-V power management.
What is the purpose of the five CTRLx pins on the TPD13S523RSVR?
The five CTRLx pins (CTRL1–CTRL5) provide interchangeable ESD protection for HDMI control lines including CEC, HPD, SCL, SDA, and UTILITY. Each pin features identical clamping characteristics (±12-kV IEC 61000-4-2), 1-pF capacitance, and bidirectional diode structure. Their interchangeability simplifies PCB layout and allows flexible assignment without performance trade-offs.
Can the TPD13S523RSVR be used in place of the TPD13S523PWR?
Yes, the TPD13S523RSVR is functionally identical to the TPD13S523PWR but housed in a smaller 2.6 mm × 1.8 mm UQFN (RSV) package versus the 5.0 mm × 4.4 mm TSSOP (PW). Both share identical electrical specs, pin functions, and thermal ratings. Layout redesign is required due to different footprints and thermal pad configuration, but no schematic changes are needed - making RSV ideal for space-constrained applications.
