Piher Sensing Systems launches a TMR current sensor that generates a ratiometric analog output voltage signal proportional to the current flowing through the integrated conductor. Compared to conventional Hall-effect current sensors, this sensor provides more accurate measurement, a higher sampling rate and lower temperature drift. It has been designed for accurate measurement of currents in automotive battery management and motor control applications.
