Melexis introduces two new parts to its programmable digital Hall-effect sensor line. The MLX92231 and MLX92211 feature EEPROM memory, allowing magnetic switching thresholds (including hysteresis) to be configured. Both are factory pre-programmed to precise Hall-effect switch or latch specifications to provide tailored results that match specific application requirements.
The MLX92211 targets applications requiring Hall-effect latch magnetic characteristics while the MLX92231 supports applications for Hall-effect switch magnetic behaviour. A novel 32-bit unique ID code in each sensor gives lifetime traceability.
Constructed on a proprietary mixed signal CMOS process technology, the MLX92231 and MLX92211 ICs integrate 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 programmable architecture enables high accuracy switching thresholds and an integrated factory programmed thermal compensation value to be set. 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), these AEC-Q100-qualified devices are highly suited to use in the most demanding of automotive and industrial settings.
