Abstract
USB controllers, systems and methods are presented to conserve power in a USB controller, in which a transmitter transmits data to a line of a connected USB cable according to a transmit data signal, and a pull down circuit selectively sinks current from a supply node of the transmitter when the transmit data signal is in a first state, refrains from sinking the first current from the supply node when the transmit data signal is in a different second state.
