The LTC4418CUF connects one of the two active supplies to a common output based on priority and validity. Connects to a common output based on priority and validity. Priority is determined by pin assignment, with V1 having a higher priority and V2 having a lower priority. The power supply is defined as valid when the supply voltage is continuously within the overvoltage (OV) and undervoltage (UV) ranges. If the highest priority valid input exceeds the OV/UV window, the channel is immediately disconnected and the other valid inputs are immediately disconnected while the other valid input is connected to the common output. Multiple LTC4418CUFs as well as and three-channel LTC4417 can be cascaded to provide switching between more than two inputs.
