GATE_VSYS (pin 20)

The GATE_VSYS pin (pin 20) can be connected with a trace (recommended 6mil trace width) to the gate pins of the N-ch MOSFET with source tied to PPHV. It is recommended to NOT via directly to the gate pin of the N-ch MOSFET, instead use via(s) to connect the GATE_VSYS pin from the TPS25751S to the gate pin of the N-ch MOSFET. Refer to figure 10-21 and figure 10-22 for examples on how to connect the traces.

GATE_VBUS (pin 21)

The GATE_VBUS pin (pin 21) can be connected with a trace (recommended 6mil trace width) to the gate pins of the N-ch MOSFET with source tied to VBUS. It is recommended to NOT via directly to the gate pin of the N-ch MOSFET, instead use via(s) to connect the GATE_VBUS pin from the TPS25751S to the gate pin of the N-ch MOSFET. Refer to figure 10-21 and figure 10-22 for examples on how to connect the traces.
