It releases at 6.8mT, providing a clean hysteresis window for reliable switching in position and proximity sensing. The 11mT operate point and 6.8mT release point define a 4.2mT hysteresis band that prevents chatter at the switching threshold. For a procurement decision, this means the sensor is suited to applications with moderate magnetic field gradients — think ferrous-target proximity or magnet-in-plastic assemblies — rather than sub-millimeter gap sensing. The current-source output (max 7.8mA) simplifies wiring: a single pull-up resistor to the ECU's input converts the current to a voltage, and the 2-wire topology reduces harness cost. ## Automotive-grade temperature and supply The 2.7V to 38V supply range handles cold-crank dips and load-dump transients without external clamping — a genuine BOM simplification. The 18mA max supply current is typical for a 2-wire Hall switch; budget it in the module's quiescent current calculation if the sensor is always powered. ## Package and footprint Supplied in a SOT-23-3 package (TO-236-3 / SC-59 compatible), the part is a drop-in for standard three-pin Hall-switch footprints. The surface-mount package suits automated assembly and reflow soldering. ## Lifecycle and compliance It is ROHS3 compliant.","metaTitle":"TMAG5124G1CEDBZRQ1 Hall-Effect Unipolar Switch, 11mT Trip","metaDescription":"Texas Instruments TMAG5124G1CEDBZRQ1 automotive Hall-effect unipolar switch, 2.7V-38V supply, 11mT trip/6.8mT release, -40°C to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Unipolar Switch","Technology":"Hall Effect","Output Type":"Current Source","Polarization":"South Pole","Mounting Type":"Surface Mount","Sensing Range":"11mT Trip, 6.8mT Release","Package / Case":"TO-236-3, SC-59, SOT-23-3","Test Condition":"-40°C ~ 150°C","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 38V","Operating Temperature":"-40°C ~ 150°C (TA)","Current - Output (Max)":"7.8mA","Current - Supply (Max)":"18mA","Supplier Device Package":"SOT-23-3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.30000","currency":"USD"},{"qty":10,"price":"$1.16300","currency":"USD"},{"qty":25,"price":"$1.10400","currency":"USD"},{"qty":100,"price":"$0.90690","currency":"USD"},{"qty":250,"price":"$0.84780","currency":"USD"},{"qty":500,"price":"$0.74920","currency":"USD"},{"qty":1000,"price":"$0.59148","currency":"USD"},{"qty":3000,"price":"$0.55800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4c0a7ae4194130de540007f894020dc4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TMAG5124G1CEDBZRQ1 suitable for automotive applications?","answer":"The 2.7V to 38V supply range handles automotive voltage transients."},{"question":"What is the replacement or equivalent for TMAG5124G1CEDBZRQ1?","answer":"The TMAG5124G1CEDBZR is the same device without the 'Q1' automotive qualification suffix.
