ABSTRACT:
The present invention provides an improved motor current sensor and methods thereof. A first embodiment of the present invention provides a circuit having a signal transfer unit for receiving first and second input signals from opposing terminals of a shunt resistor and a signal conditioner unit for conditioning output signals from the signal transfer unit for a low power control unit. A second embodiment of the present invention provides a circuit having a signal conditioner unit for receiving first and second input signals from opposing terminals of a shunt resistor and delivering output signals to a signal transfer unit and finally to a level shifter for providing first and second voltage signals to a control unit.
