Product Information

Micronas has announced a plan to phase out this item. Please read this notice for more information. Recomended replacement items are Micronas HAL830 and HAL835 sensors. 
      
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. The HAL 810 is programmable by modulating the supply voltage. No additional programming pin is needed. The easy programmability allows a 2-point calibration by adjusting the output signal directly to the input signal (like mechanical angle, distance, or current). Individual adjustment of each sensor during the customer’s manufacturing process is possible. With this calibration procedure, the tolerances of the sensor, the magnet, and the mechanical positioning can be compensated in the final assembly. This offers a low-cost alternative for all applications that presently need mechanical adjustment or laser trimming for calibrating the system. The sensor is designed for hostile industrial and automotive applications and operates with a supply voltage of typically 5 V in the ambient temperature range from -40°C up to 150°C. The HAL 810 is available in the very small leaded packages TO92UT-1 and TO92UT-2
