A few drawbacks of using conventional Hall-effect sensors in current sensing applications have been a general limitation in accuracy, of the zero ampere output voltage and Hall amplifier sensitivity over changes in temperature as well as the output signal bandwidth and output noise. Allegro has developed a family of innovative, fully integrated, current sensor packages that are ideally suited for inverter applications that drastically improve the offset, sensitivity and bandwidth operation of Hall based current sensor ICs. In each of the sensor packages, the IC itself is the most important component and contains a precision Hall-effect element that is coupled to a low-offset, high-accuracy amplifier. These fully integrated current sensor ICs are produced in patented small form factor packages with low resistance to maximize performance in a small footprint.
