DESCRIPTION
The TPD5S115 is an integrated HDMI companion chip solution. The device provides a regulated 5 V output
(5VOUT) for sourcing the HDMI power line. The regulated 5 V output supplies up to 55 mA to the HDMI receiver.
The TPD5S115 features two control signals EN and LS_OE. The control of 5VOUT and the hot plug detect
(HPD) circuitry is independent of the LS_OE control signal and is controlled by the EN pin. The EN pin allows the
detection scheme (5VOUT + HPD) to be active before turning on the whole HDMI link. The LS_OE activates the
internal LDO, CEC, SCL, and SDA buffers only when EN is also activated. This dual stage enable scheme
ensures optimized power saving for portable applications.
There are three non-inverting bi-directional translation circuits for the SDA, SCL, and CEC lines. Each have a
common power rail (VCCA) on the A side from 1.1 V to 3.6 V. On the B side, the SCL_B and SDA_B each have
an internal 1.75 kΩ pull-up connected to the regulated 5 V rail (5VOUT). The DDC (SCL_B and SDA_B) pins
meet the I2C specification and drive up to 750 pF loads. The CEC_B pin has an internal 27 kΩ pull-up to an
internal 3.3 V supply. The TPD5S115 exceeds the IEC61000-4-2 (Level 4) ESD protection level. This device is
offered in a space saving 1.72 mm × 1.72 mm WCSP package with 0.4 mm pitch.
