Part Number: TUSB8041-Q1

Hello, could you tell me what the purpose of PWRCTL_POL? Is this to support external power switch's Enable polarity? 

  • Hi,

    PWRCTL_POL controls behavior of PWRCTL pins. This correct, this pins allow customer to support both active high and active low EN pins on there power switch. Connect a 4.7-kΩ pull-down resistor to GND or leave NC to use internal pull-up resistor. This indicates active high polarity for the PWRCTL pins on the downstream ports.

    Best, 

    Malik
