Profile: Micronas GmbH supplies cutting-edge sensor and IC system solutions for automotive & industrial electronics. We offer hall-effect sensors and embedded microcontrollers for automotive & industrial applications. The HAL® 1000 is a programmable hall switch. The sensor characteristics, the two switching points Bon and Boff, are programmable for the application. The sensor can be programmed to be unipolar or latching, sensitive to the magnetic north pole or sensitive to the south pole, with normal or with an electrically inverted output signal. It is based on the HAL 8xx family and features a temperature-compensated hall plate with choppered offset compensation, an A/D converter, digital signal processing, a push-pull output stage, 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.
