Melexis has announced the MLX92212 family of digital output Hall effect sensors.
Built on an advanced cmos process, the AEC-Q100 qualified devices are said to require significantly less operating current than competing devices.
The MLX92212LSE-AAA low hysteresis bipolar latch and MLX92212LSE-ABA high hysteresis unipolar switch are optimised for 2.5 to 5.5V operation, making them suitable for pairing with many low power microcontrollers in embedded systems.
Both the sensor and specified microcontroller can thereby share the same power rail. The sensors' open drain outputs allow simple connectivity with TTL/CMOS logic. They exhibit minimal magnetic switch point drift over temperature (up to 150°C) or lifetime and can withstand 8kV electro static discharge.
The MLX92212LSE-AAA is designed for use with multi-pole ring magnets or alternating magnetic fields. It is highly suited for BLDC motor commutation, speed sensing and magnetic encoder applications.
Typical automotive uses include anti-trap/anti-pinch window lift controls, automatic door/hatch systems and automatic power seat positioning.
