Abstract:
The present disclosure includes circuits and methods for controlling skin temperature of an electronic device. In one embodiment, a thermal sensor is configured on a case of a handheld electronic device. The thermal sensor is coupled to a battery charger having a current limit circuit. If the sensed temperature of the case increases above a threshold, a current limit is reduced to reduce current in the battery charger.
