Abstract
A current sensor integrated circuit including a magnetic field sensing element, a current conductor, an insulation structure, and a power calculation circuit is configured to meet safety isolation requirements. Isolation resistors allow for voltage from a high voltage side to be sensed at a low voltage side of the circuit. The insulation structure, current sensor package, and isolation resistors can achieve at least 500 Vrms isolation.
