Abstract
An electronic device includes a load device and a power management integrated circuit. The power management integrated circuit is configured to calculate a load power value and provide the load power value to the load device in response to a request from the load device. The power management integrated circuit includes a plurality of regulators and a controller. Each of the plurality of regulators includes a current meter for measuring a load current value to be provided to the load device, and the controller is configured to calculate the load power value by using the load current value measured by the current meter and a load voltage value provided from each of the plurality of regulators to the load device.
