Discussion - Hardware / Configuration of the FT233HPQ Eval board for external Vin
« on: March 24, 2023, 12:41:32 PM »
Hi there,
Can you explain me the method how to apply and use external Vin on this board. In the factory config the "Pass through mode" is active and when I connect an PD delivery capable charger to PD2 (sink only) port then its PDOs are offered to the device connected to PD1. Hence, a power swap is initiated and the device connected to PD1 becomes a sink at the end. On the contrary, if I connected an external voltage to Vin or a non-PD capable charger to PD2 nothing happens. Obviously I need to switch of the "Pass through mode", but what else is needed to initiate a power swap on PD1?
Thanks,
Janos
