MLX92221 and MLX92241 Hall Effect Sensors

The MLX92221 and MLX92241 Hall Effect sensors from Melexis are designed to deliver the high levels of performance and robustness needed for the stringent requirements of automotive applications such as seat positioning systems, seat adjusters, seatbelt buckle switches, wipers and motor commutation systems.

These devices are equipped with an EEPROM memory, allowing the setting of customer specific parameters for magnetic switch points, output polarity, IOFF current and magnet material temperature compensation coefficient. The customer’s ability to specify tailored characteristics will enable improvements to their sensor module yields, bill-of-materials (BOM) costs and performance capabilities.

With a wide programmable magnetic range, the MLX92221 and MLX92241 both feature Hall Effect sensing elements operating from 2.7 V to 24 V voltage levels, allowing automotive, consumer and industrial applications to all be addressed. These devices integrate protection mechanisms to guard against electro-static discharge (ESD), reverse supply voltage and thermal overload. The reverse supply voltage protection protects the devices against incorrect connection of the supply line, up to -24 V.
