Abstract:
1. A system for managing battery slump in a battery-powered communication device comprising an amplifier for amplifying wireless communication signals being transmitted by the communication device, the system comprising: an input signal terminal for receiving battery voltage level information for a battery of the communication device; an output signal terminal for sending a signal for terminating a given transmission of a wireless communication signal being transmitted by the communication device, wherein the battery slump is caused by current drain on the battery during the given transmission; a controller connected to the input signal terminal and the output signal terminal, wherein the controller: a trigger input terminal connected to the controller for receiving a signal indicating when the given transmission of the wireless communication signal is beginning; wherein the controller receives the battery voltage level information when the given transmission of the wireless communication signal is occurring, and delays monitoring of the battery voltage level information for a predetermined time after receiving the signal indicating when the given transmission of the wireless communication signal is beginning.
