MLX92255LSE-AAA-001-SP Melexis

MLX92255LSE Dual Hall Effect Latch with two Speed Outputs 1. Features and Benefits With latching magnetic characteristics, both speed Operating Voltage from 2.7V to 5.5V outputs (OUT1, OUT2) are turned low or high respectively with a sufficiently strong South or Two Integrated Hall plates for Direction North pole facing the package top side. When Detection removing the magnetic field, the device keeps its Latching Magnetic Characteristics previous state. Feedback loop during power-on During Startup communication with the IC is possible to load the previous state into the 2. Application Examples registers of our IC. This will then be used as a starting point. Windows lifter with Anti-Pinch feature Rotation speed & direction detection The MLX92255 is delivered in a Green compliant 5-pin Thin Small Outline Transistor (TSOT) for Linear speed & direction detection surface-mount process. Angular position detection Power closures with Anti-Pinch features The block diagram is shown on Figure 1. VDD (+5V) 3. Description 5V The Melexis MLX92255 is a second generation Regulator Hall-effect dual latch designed in mixed signal amplifier Open-Drain OUT1 Output CMOS technology. The device integrates a voltage amplifier Open-Drain regulator, two Hall sensors with advanced offset OUT2 Output cancellation system and two open-drain output Control Reference drivers, all in a single package. Logic Two Hall plates are integrated on the same piece GND of silicon, thus using the high precision of the wafer fabrication process to ensure a fixed Figure 1 spacing of 1.45mm between the sensing elements. 390109225501 Page 1 of 12 Datasheet Rev.002 Apr/2018 MLX92255LSE Dual Hall Effect Latch with two Speed Outputs Contents 1.
