Abstract

In one embodiment of the cold end switch battery management control method, a battery generates an output voltage at a positive terminal thereof. A first control voltage is also generated by an integrated circuit. A gate of a field effect transistor (FET) receives the first control voltage, wherein the FET comprises a drain and a source with the source coupled to a negative terminal of the battery. The FET transmits current towards the battery in response to the gate receiving the first control voltage, wherein the first control voltage is greater than the output voltage, and wherein the first control voltage is less than a breakdown voltage of the integrated circuit.
