Description
This TI Precision Verified Design provides a complete closed loop Hall based current transducer signal conditioning solution. The circuit features the DRV411 and is designed to accurately measure dc, ac and pulsed currents to +/-50 A with galvanic isolation between the primary and secondary circuits. The DRV411 provides Hall excitation, a compensation coil driver and a precision difference amplifier in a single package. The unique current spinning technology employed on the DRV411 virtually eliminates the offset and 1/f noise of the Hall device and enables accurate, galvanically isolated, high-current, measurements in applications such as industrial motor control, energy, and HEV.
