Texas Instruments TPD5S116YFFR

Overview

TPD5S116YFFR from Texas Instruments is an HDMI companion IC integrating ESD protection, auto-direction-sensing I²C level shifters (SCL/SDA/CEC), a 55-mA current-limited 5-V load switch, hot-plug detect with glitch filtering, and utility-pin ESD protection. It supports HDMI 1.3/1.4/2.0 interfaces, eliminates external termination resistors for HPD/CEC/SCL/SDA, and powers CEC from an internal 3.3-V node - enabling compact portable media player and tablet HDMI port designs.

For engineers reviewing the TPD5S116YFFR datasheet, TPD5S116YFFR pinout, TPD5S116YFFR application, or TPD5S116YFFR equivalent, key selection criteria include ±15-kV IEC 61000-4-2 contact ESD rating on connector-side pins, 750-pF capacitive drive capability on SCL/SDA lines, reverse-current blocking at 5V_CON and HPD_CON, thermal shutdown at 166°C, and DSBGA-15 (2.13 mm × 1.33 mm) package compatibility with high-density mobile PCB layouts.

Technical Context

The TPD5S116YFFR implements three independent bi-directional level-shifting translation circuits - one each for SCL/SDA, CEC, and HPD - with separate VCCA (1.1–5.5 V) and 5V_CON (4.5–5.5 V) supply domains. Each shifter includes input hysteresis (40–500 mV), internal pull-up/pull-down resistors, and back-drive protection to prevent leakage during system power-off.

Its integrated 55-mA load switch features under-voltage lockout (2.85 V rising threshold), 3-µs deglitching against false shorts, 38.5-mV output voltage drop at 55 mA, and thermal shutdown with 23°C hysteresis. The HPD path includes a dedicated 10-µs glitch filter and programmable pull-down to avoid false detection during HDMI connector insertion.

FAQ

What is the maximum capacitive load the TPD5S116YFFR can drive on the SCL/SDA lines?

The TPD5S116YFFR guarantees operation with ≥750 pF bus capacitance on SCL_CON and SDA_CON lines across all supported VCCA voltages (1.1 V to 5.5 V), exceeding the HDMI 2.0 specification requirement and enabling reliable DDC communication over long cables or multi-device configurations. This performance is validated in Sections 7.12–7.25 of the SLVSBP3C datasheet. The TPD5S116YFFR achieves this via boosted pull-up current (13 mA) and optimized rise/fall times.

Does the TPD5S116YFFR require an external 3.3-V supply for the CEC function?

No, the TPD5S116YFFR does not require an external 3.3-V supply for CEC. It integrates an internal 3.3-V regulator that powers the CEC_CON pin directly, eliminating the need for a separate 3.3-V rail on the PCB. The CEC_SYS pin operates from VCCA (1.1–5.5 V), while CEC_CON is referenced to the internal 3.3-V node - a key integration advantage confirmed in the "Description" and "Pin Functions" sections of the TPD5S116YFFR datasheet.

How does the TPD5S116YFFR prevent back-powering when an HDMI source is connected to a powered-off system?

The TPD5S116YFFR prevents back-powering through active reverse-current blocking at 5V_CON, HPD_CON, SCL_CON, SDA_CON, and CEC_CON pins. When the system is powered off (VCCA = 0 V, 5V_SYS = 0 V), leakage current into these pins is limited to ≤5 µA per pin, as specified in Section 7.5 (IOFF parameter). This ensures no unintended power-up or logic corruption occurs - a critical safety feature for portable devices with always-connected HDMI ports.

What is the purpose of the UTI_CON pin on the TPD5S116YFFR?

UTI_CON on the TPD5S116YFFR provides ESD protection for the HDMI connector's utility pin - commonly used for analog audio return channel (ARC) or Ethernet-over-HDMI (HEC) return paths. It features 6-V reverse stand-off voltage, 10-V clamp voltage at 5-A IEC 61000-4-2 strike, and only 5.5-pF line capacitance to preserve signal integrity. This dedicated protection avoids compromising audio fidelity or Ethernet performance, as detailed in Section 7.10 of the SLVSBP3C datasheet.

Can the TPD5S116YFFR be used in HDMI 2.0 applications?

Yes, the TPD5S116YFFR is explicitly qualified for HDMI 2.0 applications. It meets HDMI 2.0 electrical requirements including >750-pF capacitive drive on SCL/SDA, sub-10-ns rise/fall times at 3.3-V VCCA, and full compliance with HDMI 1.3/1.4/2.0 control and 5VOUT tests without external components. TI's revision history (May 2015) confirms HDMI 2.0 compliance was added as a key update to the SLVSBP3C datasheet.
