Controlling a thermally sensitive over-current protector
A method for controlling a thermally sensitive over-current protector is described. A battery current is monitored. It is then determined whether or not the monitored current has exceeded a predetermined threshold during the entirety of a predetermined time interval. If yes, then a current source is signaled to raise its current, so as to increase the heat being generated by a heating element that is being driven by the current source thereby tripping the thermally sensitive over-current protector. Other embodiments are also described and claimed.
