General Description The Melexis MLX92221 is a new generation of Hall-effect switches designed in mixed signal submicron CMOS technology. The device integrates a voltage regulator, Hall sensor with advanced offset cancellation system and a current sinkconfigured output driver, all in a single package. Based on a brand-new platform, the magnetic core is using an improved offset cancellation system allowing faster and more accurate processing while being temperature insensitive and stress independent. In addition, a temperature coefficient is implemented to compensate the natural behaviour of certain types of magnets becoming weaker with rise in temperature. REVISION 005 – JUNE 29, 2022 390109222102 Comment BU (Bulk) RE (Reel) The included voltage regulator operates from 2.7 to 24V, hence covering a wide range of applications. With the builtin reverse voltage protection, a serial resistor or diode on the supply line is not required so that even remote sensors can be specified for low voltage operation down to 2.7V while being reverse voltage tolerant. 1. Functional Diagram Voltage Regulator with Reverse Polarity Protection Package Code UA (TO92-3L) SE (TSOT-23) In an event of a drop below the minimum supply voltage during operation, the under-voltage lock-out protection will automatically freeze the device, preventing the electrical perturbation to affect the magnetic measurement circuitry. The output current state is therefore only updated based on a proper and accurate magnetic measurement result. The two-wire interface not only saves one wire, but also allows implementation of diagnostic functions as reverse polarity connection and malfunction detection. The on-chip thermal protection also switches off the output if the junction temperature increases above an abnormally high threshold. It will automatically recover once the temperature decreases below a safe value. With latching magnetic characteristics, the supply current state is turned high by a sufficiently strong South Pole facing the package branded side. Toggling the state of the supply current from high to low is possible by applying low or no magnetic field. The MLX92221 is delivered in a Green and RoHS compliant Plastic Single-in-Line (TO-92 flat) for through-hole mount or PCB-less design or in 3-pin Thin Small Outline Transistor (TSOT) for surface mount process Page 1 of 17 MLX92221-AAA 2-Wire Hall Effect Latch Contents Features and Benefits ................................................................................................................................ 1 Applications ............................................................................................................................................... 1 Ordering information ................................................................................................................................. 1 1.
