MLX92221-AAA 2-Wire Hall Effect Latch Features and Benefits Application Examples Wide operating voltage range: from 2.7V to 24V Integrated self-diagnostics Chopper-stabilized amplifier stage Programmable Built-in negative temperature coefficient Reverse Supply Voltage Protection Under-Voltage Lockout Protection Thermal Protection High ESD rating / Excellent EMC performance Automotive, Consumer and Industrial Wiper motor Window lifter Seatbelt buckle Seat positioning Sunroof/Tailgate opener Electrical power steering Ordering Information Part No. MLX92221LUA-AAA-xxx-BU MLX92221LSE-AAA-xxx-RE Temperature Code L (-40°C to 150°C) L (-40°C to 150°C) Package Code UA (TO92-3L) SE (TSOT-23) The included voltage regulator operates from 2.7 to 24V, hence covering a wide range of applications. With the built-in 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 VDD Voltage Regulator with Reverse Polarity Protection UnderVoltage Lockout TEST Temperature Compensation Switched Hall Plate Bop/Brp reference Thermal Protection 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. Output Current Sink CDS Amplifier Control Trimming Register GND 2 General Description The Melexis MLX92241 is a new generation of Halleffect switches designed in mixed signal submicron CMOS technology. The device integrates a voltage regulator, Hall sensor with advanced offset cancellation system and a current sink-configured 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. 390109224100 Rev. 1 Comment BU (Bulk) RE (Reel) 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 14 June/13 MLX92221-AAA 2-Wire Hall Effect Latch Table of Contents 1 Functional Diagram .................................................................................................................... 1 2 General Description.................................................................................................................... 1 3 Absolute Maximum Ratings ....................................................................................................... 3 4 General Electrical Specifications .............................................................................................. 4 5 Specifications ............................................................................................................................. 5 5.1 MLX92221LSE-AAA-001 ........................................................................................................................................... 5 5.2 MLX92221LSE-AAA-002 ........................................................................................................................................... 5 5.3 MLX92221LSE-AAA-003 ........................................................................................................................................... 5 5.4 MLX92221LUA-AAA-004 ........................................................................................................................................... 5 5.5 MLX92221LUA-AAA-005 ........................................................................................................................................... 6 5.6 MLX92221LUA-AAA-006 ........................................................................................................................................... 6 6 Magnetic Behaviour .................................................................................................................... 7 6.1 Latch sensor .............................................................................................................................................................. 7 7 Performance Graphs .................................................................................................................. 8 7.1 IOFFLow vs. TJ ............................................................................................................................................................... 8 7.2 IOFFHigh vs. TJ.............................................................................................................................................................. 8 7.5 ION vs. TJ .................................................................................................................................................................... 8 7.4 IOFFLow vs. VDD ............................................................................................................................................................ 8 7.5 IOFFHigh vs. VDD ............................................................................................................................................................ 8 7.6 ION vs. VDD .................................................................................................................................................................. 8 7.7 VDD de-rating UA package ......................................................................................................................................... 9 7.8 VDD de-rating TSOT package ..................................................................................................................................... 9 8 Application Information............................................................................................................ 10 8.1 Typical Automotive Application Circuit ..................................................................................................................... 10 8.2 Automotive and Harsh, Noisy Environments Application Circuit .............................................................................. 10 8.3 Strobing VDD application (used for reduced self-heating) ......................................................................................... 10 9 Standard information regarding manufacturability of Melexis products with different soldering processes ..................................................................................................................................... 11 10 ESD Precautions ..................................................................................................................... 11 11 Package Information............................................................................................................... 12 11.1 UA (TO92 -

For proper operation, a 10nF to 100nF bypass capacitor should be placed as close as possible to the VDD and ground pin. 2. The device could tolerate negative voltage down to -24V, so if negative transients over supply line VPEAK< -29V are expected, usage of the diode D1 is recommended. Otherwise only RSENSE is sufficient. When selecting the resistor RSENSE, three points are important: - the resistor has to limit IDD/IDDREV to 50mA maximum - the resistor has to withstand the power dissipated in both over voltage conditions (VRSENSE2/RSENSE) - the resulting device supply voltage VDD has to be higher than VDD min (VDD = VCC – RSENSE.IDD) 3. The device could tolerate positive supply voltage up to +27V (until the maximum power dissipation is not exceeded), so if positive transients over supply line with VPEAK> 32V are expected, usage a zener diode DZ1 is recommended. The RSENSE-DZ1 network should be sized to limit the voltage over the device below the maximum allowed.
