Micronas' HAC 830 is an addition to the family of programmable linear Hall sensors. It offers optimal electromagnetic compatibility (EMC) protection as it integrates the HAL 830 robust multipurpose die and decoupling capacitors within a single mold 3-lead package. With its integrated capacitors, the HAC 830 meets the stringent ESD and EMC requirements and eliminates the need for a PCB, thus reducing the total system size and cost.
The HAC 830 is a robust multi-purpose Hall sensor for linear displacement and angle detection below 90°. Thanks to the high temperature stability, the sensor can be used in harsh environments and its ability to detect low magnetic fields leads to reduced system costs. The HAC 830 is based on Micronas' long success in linear Hall effect sensors, full in-house manufacturing, and automotive- proven zero ppm track record.
Major characteristics such as magnetic field range, sensitivity, output quiescent voltage, and output voltage range are programmable in a non-volatile memory. The sensor features a temperature-compensated Hall plate with chopper offset compensation, an A/D converter, digital signal processing, a D/A converter with output driver, an EEPROM with redundancy, and lock function for the calibration data, a serial interface for programming the EEPROM, and protection devices at all pins.
The sensor can easily be calibrated for perfectly adjusting its output to the input signals and to compensate for any variations in the application (magnet positioning, temperature drift). This enables operation over the full temperature range with high accuracy. The calculation of the individual sensor characteristics and the programming of the EEPROM can easily be done with a PC and the application kit from Micronas.
The sensor is designed for hostile industrial and automotive applications (TJ =-40°C up to +170°C). The HAC 830 is available in the small leaded RoHS package TO92-UP and is AECQ100 qualified.
