TPD6S300A: Schematic Review

Part Number: TPD6S300A
Other Parts Discussed in Thread: TPS25810,

Team,

Please help to review the attached schematic (Specially ESD devices)

0334.USB-Schematic.pdf

The requirements are as below:

Simple USB-C port with USB 2.0 support

1) CC Pin Port Controller (with Pullups/down - no PD communication)

              (A) DFP (Downstream Facing Port) only

              (B) USB 2.0 Power Mode (max 500mA @ 5V)

2) Current limiter (Turn-off / current limit @ 500mA)

3) Overcurrent Flag/Pin

4) Enable Pin

5) ESD Protection (15kV Air/ 8 kV Cond.)

  • Hi Sanjay,

    A few recommendations for the part: 

    - The TPD6S300A needs to be in between the Type-C connector and the TPS25810. The Type-C connector should not be connected to the TPS25810. The Type-C connector's CC pins should be connected to C-CC on the TPD6S300A and the CC pins on the TPD6S300A should be connected to the TPS25810's pins. See the highlighted image from the datasheet below as an example:

    - The N.C. pins need to be connected to ground.

    - If you plan to use the dead battery resistors, short the RPD_G pins to the C_CC pins. 

    Thanks,

    Emma

  • Thanks Emma for reviewing. I have updated the schematic accordingly.
