General Description The Melexis MLX92251 is a second generation Hall-effect dual latch designed in mixed signal CMOS technology. The device integrates a voltage regulator, two Hall sensors with advanced offset cancellation system and two open-drain output drivers, all in a single package. The MLX92251 shares the MLX922xx-based platform, synonym of high performance in terms of electrical specification, magnetic specification and protection level. With latching magnetic characteristics, the speed (SP) output is turned low or high respectively with a sufficiently strong South or North pole facing the package top side. When removing the magnetic field, the device keeps its previous state. The direction (DIR) output is latched in Low or High state depending on the movement direction of the applied magnetic field, as a result of certain magnetic pulse sequence on both Hall sensors. The MLX92251 is delivered in a Green compliant 5-pin Thin Small Outline Transistor (TSOT) for surface-mount process. Two Hall plates are integrated on the same piece of silicon, thus using the high precision of the wafer fabrication process to ensure a fixed REVISION 004 – JUNE 03, 2019 390109225103 Page 1 of 13 MLX92251LSE-AxA Dual Hall Effect Latch with Speed & Direction Contents 1.
