3 Description

The TPD12S016 is a single-chip High Definition

Multimedia Interface (HDMI) device with autodirection

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 reverseTSSOP

current blocking when the system is powered off.
