HAL1860

Entry-Level Programmable Linear Hall-Effect Sensor                  HAL1860HAL1860 数据手册

简介

The HAL 1860 is a universal, value-optimized programmable Hall-Effect sensor with a ratiometric, linear analog output. The sensor can be used for magnetic field measurements, current measurements, and detection of mechanical movement, like for small-angle or distance measurements. The sensor is robust and can be used in harsh electrical and mechanical environments.

Major characteristics like magnetic field range, sensitivity, offset and the temperature coefficients are programmable in a non-volatile memory. Several output signal clamping levels can be programmed to indicate various fault conditions like under/overvoltage, under/overflow or thermal supervision.

The HAL 1860 is programmable by modulating the supply voltage with a serial telegram on the sensor's output pin. 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 tolerance of the sensor, the magnet and the mechanical positioning can be compensated in the final assembly.

The sensor is designed for industrial and automotive applications, is AEC-Q100 qualified, and operates in the junction temperature range from -40 °C up to 170 °C. The HAL 1860 is available in the very small leaded package TO92UA-2.

HAL1860

The HAL 1860 sensor is a monolithic integrated circuit produced in a proven submicron CMOS technology.

It provides an output voltage proportional to the magnetic flux through the Hall plate and proportional to the supply voltage (ratiometric behavior). Selectable clamping levels for the output voltage allow diagnostic features. The HAL 1860 includes a temperature-compensated Hall plate with spinning-current offset compensation, an A/D converter, digital signal processing, an EEPROM memory with redundancy and lock function for the calibration data and the data register information, a serial interface for programming the EEPROM, and protection devices on all pins. The IC can be programmed via supply or output pin voltage modulation.

The internal digital signal processing is a great benefit because analog offsets, temperature shifts, and mechanical stress do not degrade the sensor accuracy.
