Other Parts Discussed in Thread: TPS25750, , USB-PD-CHG-EVM-01
We are thinking about developing a electronic load kind of system to test our USB C PD charger and USB A ( unidirectional).
The system is something like this,
Now we want to test USB PD at full range and validate the circuit.
To test this circuit, Im planning a circuit something like
My questions are
a) Will the above solution will work?
b) I need around 60W of sink from (BQ25792+TPS25750) can I achieve it ?
c) Can you external uC and use BQ25792 as slave to read voltage /current etc?
d) I see BQ252972 has D+ and D- pins for backward compatibility, does that mean I can use USB A BC 1.2 to operate the controller ?
e) How to emulate battery. I want a constant current sink after regulating Vbat or Vsys to different levels such as 5V, 9V, 15V, 20V ( provided by host at Vbus). My thought was
Need your suggestion.. Thanks
