Abstract
An autonomous power supply switch with a main supply input and a backup supply input and a supply output to supply the power provided at the main supply input and to switch to the backup supply input, if the power at the main supply input is below a switch threshold. The switch includes a first switch transistor connected between the main supply input and the supply output with its gate/base connected to a first steering point of the switch and a second switch transistor connected between the backup supply input and the supply output with its gate/base connected to a second steering point of the switch; an inverter or Schmitt trigger with its input connected to the second steering point and its output connected to the first steering point and its power supply connected to the backup supply input of the switch.
