Freiburg, Germany Micronas announced the HAL 82x family of programmable Hall-effect sensors, designed to meet the latest accuracy requirements of automotive applications which includes an integrated EEPROM to store the sensor parameters. The sensor's accuracy is based on the 14-bit signal path, the integrated digital signal processing and the ratiometric 12-bit analog output. It also features a multiplexed analog output. The 12-bit D/A-converter of the HAL 82x achieves the resolution of a 14 bit-converter, while avoiding the small quantization steps. The differential non-linearity (DNL) is below one LSB.
Automobile trouble-shooting and repair is enhanced by an integrated wire-break detection system. This makes it easy for the engine control computer to detect and report problems with the car's wiring. Micronas offers a development board for design and production of the Hall sensors. The required software is available free of charge. The RoHS-compliant HAL 82x is available in the TO 92UT package, suitable for overmolding, and operates at ambient temperatures between -40°C and 150°C.
