Abstract:
An electronic device includes a power management circuit generating output for a plurality of voltage monitors that each detect whether voltages received from a test apparatus are at least a different minimum threshold. The power management circuit also generates a test enable signal indicative of whether the test apparatus is supplying the minimum required voltages to the electronic device. A control circuit receives the output for the plurality of voltage monitors and the test enable signal and generates at least one control signal as a function of the output for the plurality of voltage monitors and the test enable signal. An output circuit receives the at least one control signal and generates an interface control signal that selectively enables or disables interface with analog intellectual property packages within the electronic device, in response to the at least one control signal.
