Abstract
Systems and methods for monitoring a regulated voltage output for current consumption are disclosed. An analog component senses the current at the regulated voltage output and converts the sensed current into a digital representation, which is indicative of the sensed current. A digital component inputs and analyzes the digital representation to determine whether to generate an interrupt. The interrupt is indicative to an electronic device, which is using the regulated voltage, to modify its operation. For example, the digital component may analyze the digital representation by counting a number of system clock cycles during a part of the digital representation. The counted number of clock cycles may be compared with a threshold, which may be predetermined or dynamically selected, to determine whether to generate an interrupt. Thus, the sensed current from the regulated voltage output may be used to determine whether to modify operation of the electronic device.
