DESIGNING HIGH TDP MXM MODULE POWER SOLUTION FOR AUTONOMOUS VEHICLES

In one embodiment, a power circuit for an autonomous driving vehicle (ADV) includes a first power source having a first power rating. The circuit includes a second power source having a second power rating. The circuit includes a switch coupled to the first and second power sources, the switch being configured to determining a power operating mode of an accelerator device, where the power operating mode is one of a primary mode, a secondary mode, and a dual mode. The circuit includes a first power transistor coupled between the first power source and the accelerator device and a second power transistor coupled between the second power source and the accelerator device, where the first and second power transistors are operable according to the power operating mode.
