2-wire latching Hall-effect sensor (2nd gen) - High accuracy

MLX92221

Melexis’ Latch & Switch sensors use an innovative magnetic technology that allows the measurement of the lateral magnetic flux component.

The MLX92221 is the 2nd Gen factory programmable Hall-effect latch designed in mixed signal submicron CMOS technology.

The device integrates a voltage regulator, Hall sensor with advanced offset cancellation system, programmable digital logic and a current sink-configured output driver, all in a single package.

The MLX92221 is a factory programmable device, featuring a wide variety of parameters which can be configured according to target values determined through applications engineering development:

  • Bop
  • Brp
  • Hysteresis
  • Temperature compensation
  • Active pole
  • Output polarity
