Other Parts Discussed in Thread: BQ25798, TPS25750
Tool/software:
We are developing a sink only (for now) application but we need clarity on TPS25751's following pins:
PP5V: Can we grounded as we are not using it? does it still need to be decoupled?
VBUS: what does it connect to if PP5V is not providing it voltage/current to power LDO's (like LDO_3V3 and LDO 1v5)? can we tie it to VBUS_IN? If we tie it to VBUS_IN what will happen when PD negotiates a 20v input?
VIN_3V3: Can we ground it? does it still need to be decoupled?
Thanks for any help clarifying this!
FYI, we are using BQ25798
