Patent number: 7034503Abstract: A convenient source of charging power for portable communication devices is an integral power node of a computer data bus, such as a USB (universal serial bus) port. Unfortunately, USB ports have limited power capacity, making them generally incompatible with battery charge controllers (BCCs) which are designed to receive a steady, high capacity input. The invention provides a battery charging circuit which adjusts to the parameters of an external power supply such as a USB port by adding a regulating circuit to a standard BCC design. This regulating circuit maximizes the current drawn by the BCC, while keeping the voltage to the BCC above a preset minimum (the low voltage shut off level for the BCC). If the voltage to the BCC begins to drop, the regulating circuit reduces the current drawn, so the voltage rises and stays within the operating range of the BCC.Type: GrantFiled: October 14, 2004Date of Patent: April 25, 2006Assignee: Research In Motion LimitedInventors: Dusan Veselic, Michael F. Habicher, Jacek S. Idzik, Jonathan T. Malton

The controller allows current to flow to the over-voltage protection device only when an energy storage device is experiencing over-voltage. In allowing current to flow to the over-voltage protection device only when the voltage across the energy storage device is above a predetermined voltage, power conservation is achieved.Type: GrantFiled: September 30, 2002Date of Patent: April 25, 2006Assignee: Research In Motion LimitedInventors: Andrew D.
