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
V_CCA 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.
