TPD12S016PWR

The TPD12S016PWR is a single-chip High Definition Multimedia Interface (HDMI) device with auto-direction sensing I²C voltage level shift buffers, a load switch and integrated low capacitance high-speed electrostatic discharge (ESD) transient voltage suppression (TVS) protection diodes. A 55mA current limited 5V output (5V_OUT) sources the HDMI power line. The control of 5V_OUT and the hot plug detect (HPD) circuitry is independent of the LS_OE control signal and is controlled by the CT_HPD pin, which enables the detection scheme to be active before enabling the HDMI link. The SDA, SCL and CEC lines pull up to VCCAon the A side. On the B side, the CEC_B pin pulls up to an internal 3.3V supply rail, SCL_B and SDA_B each pull up to the 5-V rail (5V_OUT). The SCL and SDA pins meet the I²C specification and drive up to 750pF capacitive loads, exceeding the HDMI 1.4 specifications.
