Part Number: TUSB8041


Hi team,

My customer want to use TUSB8041, charge downstream port 1 but not charge port 2.

So how to set the pins, including PWRCTL1, PWRCTL2, OVERCUR1z, OVERCUR2z, PWRCTL_POL, GANGED, FULLPWRMGMTz pins, float or pull-down or pull-up? 

Appreciate your suggestions, thanks a lot.

    HI Miranda,

    A pullup should be placed on the PWRCTLx/BATENz pin for the port where they want to enable battery charging.  Please see the EVM Users Guide for more information on pin configurations.
