Patent ID: 8872579

Claim:
A power control system, comprising: a first transistor; a second transistor; an interface configured to couple a drain of the first transistor to a first conductor, and to couple a drain of the second transistor to a second conductor; a current sensor coupled to a source of the first transistor and a source of the second transistor; and a current management circuit comprising a first comparator, and a second comparator, wherein: the first comparator is configured to detect a drain voltage of the first transistor, the second comparator is configured to detect a drain voltage of the second transistor, the first and the second comparators are further configured to adjust a gate voltage of the first transistor and a gate voltage of the second transistor to keep the detected drain voltages of the first and the second transistors approximately equal by comparing the drain voltage of the first transistor and the drain voltage of the second transistor to a reference voltage.
