2.6 DC Input Jack

The xWRL6844EVM can be powered-up using the 5V to 12V DC Jack. When DC Jack is connected, the Priority switchover is given to DC-jack's Voltage at the power mux(TPS2121).

Note: After the 5V-12V power supply is provided to the EVM, TI recommends pressing the NRST switch one time to verify for a reliable boot-up state.
Note: All digital IO pins of the device (except NRESET) are not fail safe. Therefore, care needs to be taken that the digital IO pins are not driven externally without the VIO supply being present to the device.
