Abstract
Techniques for voltage discharge from a USB Power Delivery (USB-PD) VBUS line are described herein. In an example embodiment, an integrated circuit comprises a discharge control logic coupled to a first discharge circuit and to a second discharge circuit. The first discharge circuit configured to couple to a power source node on the VBUS line. The second discharge circuit configured to couple to an output node on the VBUS line. The discharge control logic is configured to independently control the first discharge circuit and the second discharge circuit to discharge the voltage on the VBUS line.
