12. A method to supply power to an accelerator device of an autonomous driving vehicle (ADV), comprising:
determining a power operating mode of the accelerator device, wherein the power operating mode is one of a primary mode, a secondary mode, and a dual mode;
configuring a switch disposed on the accelerator device to power on a first power transistor coupled between a first power source and the accelerator device to provide power from the first power source to the accelerator device when the power operating mode is in the primary mode;
configuring the switch to power on a second power transistor coupled between a second power source and the accelerator device to provide power from the second power source to the accelerator device when the power operating mode is in the secondary mode; and
configuring the switch to power on the first and the second power transistors to provide power from the first and second power sources to the accelerator device when the power operating mode is in the dual mode.
