TPS65982: Dual Port Notebook Application

Part Number:TPS65982

Hi,

If 2 TPS65982 are used for dual port notebook application, how does the device work in dead battery situation?

The secondary 982 has to receive firmware (application code) from the primary one through UART, but if type-C source is connected to the secondary, then it cannot load the app code because the primary 982 is off.

What is the best way to solve this problem? And if you have reference design for dual port notebook with 982, plase send it to me or let me know the link.

Best regards,

Sean Moon
