Abstract
Universal Serial Bus Type-C (USB-C) controllers with a floating gate driver with programmable drive strength for a wide range of USB power delivery applications in electronic devices described. A USB-C controller includes a floating gate driver and control logic. The floating gate driver includes p-channel field-effect transistors (FETs) coupled in parallel between a first terminal and a second terminal and p-channel pre-gate drivers. Each p-channel pre-gate driver is coupled to a gate of one of the p-channel FETs. The floating gate driver includes n-channel FETs coupled in parallel between the second terminal and a third terminal and n-channel pre-gate drivers, each n-channel pre-gate driver being coupled to a gate of one of the plurality of n-channel FETs. The control logic sends one or more control signals to activate a first number of p-channel pre-gate drivers and a second number of n-channel pre-gate drivers based on an output voltage.
