Team,
Please help to review the attached schematic (Specially ESD devices)
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.)
Regards,
Sanjay R. Pithadia
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
