Abstract
A system () includes a microelectronic device () including first transistors () and second transistors (), a power supply () electrically connected to the first and second transistors to provide power to the first and second transistors such that current flows through the first and second transistors, a switch () in operable communication with the second transistors, the switch allowing current to flow from the power supply through the second transistors when in a first mode of operation and preventing current from flowing from the power supply through the second transistors when in a second mode of operation, control circuitry in operable communication with the switch, and current sensing circuitry coupled to the first transistors to detect a test amount of current flowing through at least one of the first transistors when the switch is in the first mode of operation.
