Abstract
The impedance of a connector, such as a flex cable, between a source and load affects the temperature and power consumption within an electronic system, such as a mobile device. According to embodiments described in this disclosure, the impedance of the flex cable may be separately tracked from the impedance of the source, which provides for improved power management within the electronic system. The impedance of the flex cable may be factored into determining a maximum available power to the load. The impedance of the flex cable may also be mapped to a temperature and used to manage power to maintain operation within temperature limits. Additional aspects of power management and impedance tracking for a connector are described herein.
