The TPD13S523 device is a single-chip integrated IEC 61000-4-2 ESD protection solution for HDMI 1.4 or HDMI 1.3 interfaces. This device offers 13 channels of TVS diodes with flow-through pin mapping that matches HDMI connector high-speed lines. While providing ESD protection, the TPD13S523 adds little to no additional distortion to the high-speed differential signals. The monolithic integrated circuit technology ensures that there is excellent matching between the two-signal pair of the differential line (< 0.05-pF differential matching between TMDS lines). This offers an advantage over discrete ESD solutions where variations between two different ESD protection circuits may significantly degrade the differential signal quality.
The TPD13S523 incorporates an on-chip current limited load switch that is compliant with HDMI 5-V out electrical specifications. The short-circuit protection at 5V_OUT ensures that the device is not damaged in case there is an accidental short to GND. The load switch also incorporates a reverse-current blocking feature which ensures that the HDMI driver side is not erroneously turned on when two HDMI drivers are connected together.
Typical applications for the TPD13S523 include set top boxes (STB), e-books, tablets, smart phones, and camcorders.

The TPD13S523 device is a single-chip ESD solution for the HDMI transmitter port. By providing system-level ESD protection for a full HDMI port, the TPD13S523 can protect the core IC from ESD strikes and absorb the associated energy.
While providing the ESD protection, the TPD13S523 adds little-to-no signal distortion to the high-speed differential signals. In addition, the monolithic integrated circuit technology ensures that there is excellent matching between the two-signal pair of the differential line.
The TPD13S523 also provides an on-chip regulator with current output ratings of 55 mA at pin 38. This current enables HDMI receiver detection even when the receiver device is powered off.
The connector-facing I/O pins can withstand ESD events up to ±12-kV contact and ±14-kV air. An ESD clamp diverts the current to ground.
The TPD13S523 provides a complete ESD protection scheme for an HDMI 1.4 compliant port. No additional components are required for ESD protection and current-limiting besides this device.
The TPD13S523 provides an on-chip regulator with a current output rating of 55-mA. This regulator also prevents reverse current flow from occurring, in compliance with the HDMI 5-V supply specification.
This device provides protection for all control lines in HDMI, including the UTILITY pin.
The TPD13S523 has a very low capacitance variation (< 0.05 pF) between different TMDS ESD clamps. This provides excellent matching and does not degrade differential signal quality.
The TPD13S523 is offered in 2 different packages. A 16-pin industry standard TSSOP package is provided for ease of routing and easy layout. A 16-pin UQFN (RSV) is provided where small size is needed in the application.
The TMDS ESD clamps have a very low capacitance that is capable of supporting HDMI data rates exceeding 3.4 Gbps.
The TMDS ESD clamps have a very low RDYN of 0.5Ω (typ) which provides excellent ESD protection clamping characteristics for the upstream core transmitter.
The TPD13S523 is rated to operate from -40°C to 85°C.
TPD13S523 is active with the conditions in the Recommended Operating Conditions met. Each connector side pin has an ESD clamp that triggers when voltages are greater than VBR or less than the lower diode's Vf. During ESD events, voltages as high as ±12-kV contact ESD can be directed to ground through the internal diode network. Once the voltages on the protected line fall below these trigger levels (usually within 10's of nano-seconds), these pins revert to a nonconductive state.

The TPD13S523 provides IEC 61000-4-2 Level 4 Contact ESD protection for an HDMI 1.4 transmitter port. An integrated current limit switch ensures compliance with the HDMI 5-V power supply requirements. This section presents a simplified discussion of the design process for this protection device.
A typical application schematic for an HDMI 1.4 transmitter port protected by the TPD13S523 is shown in Figure 11. The eight TMDS lines and five control lines are connected to their respective pins for ESD protection. The 5-V power path is connected through the 55-mA current limit switch.
For this design example, use the parameters listed in Table 1 as input parameters.
PARAMETER | EXAMPLE VALUE |
---|---|
Voltage on 5V_SUPPLY | 4.8 V - 5.3 V |
HDMI Data Rate | 3.4 Gbps |
To begin the design process, the designer must know the following parameters:
The TPD13S523 is capable of operating the 5V_SUPPLY up to 5.5 V, with recommended voltage from 4.5 V to 5.5 V. In this example, the supply range is 4.8 V to 5.3 V, which satisfies this requirement.
The TPD13S523 is capable of operating at HDMI data rates in excess of 3.4 Gbps, compliant to the HDMI 1.4 maximum data rate. In this example, the maximum HDMI 1.4 data rate of 3.4 Gbps has been chosen.
