Abstract
Embodiments of a resistor module of a USB interface device and a method for operating a resistor module of a USB interface device are described. In an embodiment, a resistor module of a USB interface device includes a pull-down resistor connectable to a USB power-sourcing device, a switch connected between the pull-down resistor and a fixed reference voltage, an energy storage unit connectable to the USB power-sourcing device and configured to store electrical energy in response to a current from the USB power-sourcing device, a switch control unit connected to the energy storage unit and configured to control the switch with a control signal in response to a voltage of the energy storage unit, and a glitch filter connected to the switch and to the switch control unit and configured to remove a glitch in the control signal. Other embodiments are also described.
