Programmable Digital Hall Effect Sensor From Melexis Delivers Best In Class Performance, Size And Cost

Constructed on a proprietary mixed signal CMOS process technology, the MLX92232 is the first customer field programmable sensor in this family of high accuracy devices. Each IC integrates a Hall sensor element with advanced offset cancellation mechanism, a voltage regulator and an open-drain output driver in industry standard 3 pin SIP and TSOT23 packages. The flexible programming capabilities use Melexis proven PTC (Programming Through the Connector) technology to enable end of production line calibration for finished sensor modules. This method allows compensation of mechanical assembly tolerances, material variations and magnet part to part variations. The industry benchmark programmable architecture enables high accuracy switching thresholds and an integrated factory programmed thermal compensation value. These features simplify manufacturing of precision, thermally stable sensor modules using low cost magnet materials while avoiding complex, expensive temperature testing.

Covering a wide operational voltage range (2.7V to 24V) and supporting an extensive operational temperature range (-40°C to +150°C), this AEC-Q100-qualified device is highly suited to use in demanding automotive and industrial settings. Output current limit, under-voltage lockout and thermal shutdown ensure its on-going reliability, while also lowering the overall bill of materials required. Among the MLX92232’s target applications are seat positioning systems, clutch position sensors and brake light sensors.

The MLX92232’s low voltage capability, differentiates it from other Hall effect switch solutions on the market, by allowing it to interface with microcontrollers and other digital ICs placed on supply lines at
