HAL 810 Programmable Hall Effect Sensor from Micronas

The HAL® 810 is a member of the Micronas family of programmable linear Hall sensors. The linear output is provided as the duty cycle of a pulse-width modulated output signal (PWM signal).

The HAL 810 is a universal magnetic field sensor with a linear output based on the Hall effect. The IC is designed and produced in sub-micron CMOS technology and can be used for angle or distance measurements if combined with a rotating or moving magnet. The major characteristics, such as magnetic field range, sensitivity, output quiescent signal (output duty cycle at B = 0 mT), and output duty cycle range are programmable in a non-volatile memory.

The HAL 810 features a temperature-compensated Hall plate with chopped offset compensation, an A/D converter, digital signal processing, an EEPROM memory with redundancy and lock function for the calibration data, a serial interface for programming the EEPROM, and protection devices at all pins. The internal digital signal processing is of great benefit as analog offsets, temperature shifts, and mechanical stress do not lower the sensor accuracy.
