Intelligent power supply and cable system
View Patent ↗This invention includes a power supply having a plurality of cables, each corresponding to a unique electronic host device. The cable includes a memory device having predetermined power characteristics associated with an electronic host device. The cable further includes a unique mating connector for coupling to the electronic host device. The power supply includes a control circuit that reads the power characteristics and configures the power supply to charge the electronic host device. The system allows a user to carry a single power supply with multiple cables as opposed to having to transport many different power supplies.
1. An intelligent power system, comprising;
a. a power supply having a control circuit;
b. a cable having a memory device; and
c. a device specific connector for mating to a host device;
wherein the memory device has stored therein predetermined power requirements.
2. The system of claim 1 , further comprising a universal connector.
3. The system of claim 2 , further comprising a protection circuit.
4. The system of claim 3 , wherein the predetermined power requirements are selected from the group consisting of a voltage limit and a current limit.
5. The system of claim 2 , further comprising a power conversion circuit.
6. The system of claim 5 , wherein the power conversion circuit is selected from the group consisting of fly back regulator, a step-down, or “buck”, regulator, a step-up regulator, a buck-boost regulator, and a resonant regulator.
7. The device of claim 6 , wherein the memory device is an EPROM.
