3 Description

The TPD12S016 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 55-mA current limited 5-V 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 (5V_OUT and HPD) to be active before enabling the HDMI link. The SDA, SCL, and CEC lines pull up to VCCA on the A side. On the B side, the CEC_B pin pulls up to an internal 3.3-V 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 750 pF capacitive loads, exceeding the HDMI 1.4 specifications. The HPD_B port has a glitch filter to avoid false detection due to plug bouncing during the HDMI connector insertion. TPD12S016 offers reverse current blocking at the 5V_OUT pin. SCL_B, SDA_B, CEC_B pins also feature reverse-current blocking when the system is powered off.
