TPD5S115YFFR Datasheet PDF - TI

The TPD5S115 device 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 with a current limiting function. 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 noninverting, bidirectional, voltage level 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 pullup 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 with the buffers. The CEC_B pin has an internal 27-kΩ pullup to an internal 3.3-V supply. The TPD5S115 exceeds the IEC61000-4-2 (Level 4) ESD protection level. This device features a space saving, 1.72-mm × 1.72-mm, YFF package with 0.4-mm pitch.
