Dual Hall-effect latch IC with two speed outputs - Low voltage - MLX92255
Product description
The MLX92255 integrates a voltage regulator, two Hall sensors with advanced offset cancellation system and two open-drain output drivers, all in a single package.
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 spacing of 1.45 mm between the sensing elements.
With latching magnetic characteristics, both speed outputs (OUT1, OUT2) are 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 MLX92255 is delivered in a Green compliant 5-pin Thin Small Outline Transistor (TSOT) for surface-mount process.

Lateral sensing with integrated IMC for DC/BLDC motor applications
As brushless DC (BLDC) motors become an increasingly popular choice for many applications including blowers, cooling fans and pumps, more sophisticated control is required. By integrating an IMC into products, such as the MLX92211 IC, surface mount sensing is available, thereby simplifying the production process and reducing the space required.
