Part Number: TPS25947
Other Parts Discussed in Thread: TPS66020,

Tool/software:

Hi ~

Is the following correct? 

For type C PD application, is TPS259474 generally more feasible? (condition: intel Gothic bridge, TYPE C pd adaptor 65W & 100W) 

Key Differences

  • Voltage Range: TPS66020 supports a higher voltage range for the sink path (up to 22V) compared to TPS259474 (up to 23V).
  • Current Capacity: TPS259474 can handle slightly higher current (up to 5.5A) compared to TPS66020 (up to 5A for sink path).
  • Protection Features: Both devices offer comprehensive protection features, but TPS259474 includes additional features like true reverse current blocking and adjustable transient blanking timer.

    Hi Eve,

    TPS66020 is more towards PD controller type part with integrated FETs for dedicated SRC and SNK paths. TPS25947 is a simple back-to-back FET device with primary focus on protections. TPS25947 do not allow reverse current. 

    I am not aware of Intek Gothic bridge. I am assuming you don't need bi-directional current flow so in that case TPS25947 is better for its simplicity and protection features.

    If you require bi-directional current flow, then go with TPS66020.

    Best Regards,
