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.

A host interface for a storage module may include an out-of-band (OOB) detector that is configured to detect receipt of an OOB signal using a clock signal. The clock signal may be generated by a clock generator that is activated using a counter. When an OOB signal is received, the counter may activate the clock generator. When no OOB signal is being received, the counter may wait for a predetermined time period before deactivating the clock generator.

A charge pump provides matched charging and discharging currents. One transistor is connected to an input of a charge pump core while two transistors are connected to the other input of the charge pump core, with each of the transistors mirroring a reference transistor through different mirroring pathways so that current through the transistor of the first input is equal to the sum of currents through the two transistors of the second input.
