TPS65987D: Power role swap

Part Number: TPS65987D


Hi all,

We are designing one system in which we are using TPS65987D pd controller..We have one usb type c plug( male) connector which gets connected to the mobile...also we have usb type c receptacle which is used for charging purposes...we have one battery charger and battery along with it....
Operation: if the battery is full the pd controller ( present on our board) should act like source and delivers power to the usb type c plug(mobile pd controller acting as sink)...if the battery is low, mobile pd controller should act as source i.e mobile should delivers power to our board( our board pd controller should act as sink)...
Whether this communication takes place automatically in pd controller or do we need to take care using an external microcontroller?

  • What battery charger are you planning to use?  The TPS65987D does have some level of ability to manage a charger, but it will be limited. 

    Most systems with a battery charger also have a small MCU that manages the charger.  This MCU can also manage the TPS65987D.
