Embodiment Construction

[0019] Electronic devices can rely on one or more stable, regulated voltages for their operation. Regulated voltages can be generated by various electronic components. One type of electronic component is a voltage regulator. A voltage regulator is configured to maintain a constant voltage level. Regulators can be designed in several ways, such as by using a feed-forward design or by using a negative feedback control loop.

[0020] One specific type of regulator is a low dropout (LDO) regulator. An LDO regulator is a DC linear regulator that can regulate the output voltage even when the supply voltage is very close to the output voltage. Other types of regulators are contemplated.

[0021] The voltage output by the voltage regulator can be supplied to various electronic devices. One type of electronic device is a memory device. Other types of electronic devices are also contemplated. As discussed in more detail below, a memory device may include various modules or functi...

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.

Description

[0001] References to related applications [0002] This application claims priority to US Application Serial No. 14 / 637,117 (filed March 3, 2015), which is hereby incorporated by reference in its entirety. technical field [0003] The present application generally relates to monitoring operations in electronic devices. More specifically, the present application relates to dynamically monitoring current consumption in electronic devices. Background technique [0004] Electronic devices often include one or more regulators. Voltage regulators are designed to generate a stable voltage to power loads in electronic equipment. Under heavy load conditions, the voltage generated by the regulator may drop. To avoid this, the voltage at the output of the regulator is monitored to determine when the load is too high. Contents of the invention [0005] According to one aspect, a monitoring device is disclosed. The monitoring device is configured to monitor current consumption on ...
