描述 Description

The MLX92211 targets applications requiring Hall-effect latch magnetic characteristics. Constructed on a proprietary mixed signal CMOS process technology, the MLX92211 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. Output current limit, under-voltage lockout and thermal shutdown ensure on-going reliability, while also lowering the overall bill of materials required. Target automotive applications for the MLX92231 and MLX92211 include seat positioning systems, clutch position sensors, brake light sensors. Both ICs are also suitable for industrial position sensing roles in robotics, factory automation equipment, material handling, valve positions and process controls.
The MLX92211 feature a low voltage capability, differentiating them from other Hall-effect sensor solutions on the market, by allowing them to interface with microcontrollers and other digital ICs placed on supply lines at <3V. This maximizes their versatility and permits incorporation into system designs that are beyond the scope of competing devices. The built-in reverse voltage protection feature does not require a serial resistor or diode on the supply line, so that even remote sensors can be specified for low voltage operation down to 2.7V while still being reverse voltage tolerant.
