Abstract: A method and apparatus for parameter-based sensor selection is disclosed. In one embodiment, a system includes an integrated circuit (IC) having a first power management circuit, and a second power management circuit external to the IC. The IC includes various functional units implemented in various power domains, while the second power management circuit (which may be implemented on an IC) includes a number of voltage regulators for providing power to the power domains. The second power management circuit also includes sensors that provide data about a system parameter, with the data being provided at telemetry to the first power management circuit. When the system parameter is less than a first threshold, the telemetry data may be based on a first sensor. When the system parameter is greater than the first threshold, the telemetry data may be based on a second sensor.

Abstract: An on-chip digital communication interface circuit is to be directly coupled to a counterpart interface circuit of a separate battery-side gas gauge circuit. An on-chip battery charging control circuit controls battery charging voltage and current that is supplied from a separate power source interface circuit to a battery cell terminal, according to charging voltage and current limits. The charging limits are read from the gas gauge circuit and in effect carry out a selected one of several different battery charging profiles. Other embodiments are also described and claimed.
