Abstract: Methods and apparatus for power monitoring using power management integrated circuits. In some implementations, a power management integrated circuit includes multiple voltage regulators, an analog multiplexer, an analog to digital converter, power determination circuitry, and control circuitry. The analog multiplexer has multiple inputs that are each configured to receive an analog input signal indicative of an amount of electrical current output by a different one of the multiple voltage regulators. The analog-to-digital converter is configured to receive analog output signals from of the analog multiplexer and to provide a digital output. The power determination circuitry configured to determine a power output level for each of the multiple voltage regulators based on respective digital outputs of the analog-to-digital converter. The control circuitry is configured to control the analog multiplexer to periodically change which of the analog input signals is passed to the output of the analog multiplexer.

Abstract: An example method includes, responsive to determining that a button of a mobile computing device has been pressed for longer than a first amount of time, resetting a power management integrated circuit (PMIC); responsive to determining that the button of the mobile computing device has been pressed for longer than a second amount of time that is longer than the first amount of time, electrically disconnecting, at a first time, power sources from the mobile computing device; and electrically reconnecting, at a second time that is after the first time, the power sources to the mobile computing device.
