It detects a south-pole magnetic field and switches an open-drain output low when the flux density exceeds 36 mT, releasing at 15.9 mT. The part is designed for position and proximity sensing in powertrain, chassis, and body electronics where the ambient temperature can hit 170°C at the junction. Because it is a unipolar switch, it responds only to one magnetic polarity — south pole. That means the magnet must be oriented correctly in the assembly; a north-pole field will not trigger it. This is not a latching or bipolar device, so the output returns high when the field drops below the release point. ## Magnetic thresholds and what they mean for the air gap The 36 mT operate point and 15.9 mT release point define the hysteresis band, which prevents chatter at the switching threshold. The open-drain output sinks up to 25 mA and requires an external pull-up resistor to the supply rail. The 3 V supply is the nominal operating voltage.","metaTitle":"TLE49642MXTMA1 Unipolar Hall Switch – Infineon, AEC-Q100","metaDescription":"TLE49642MXTMA1 from Infineon: AEC-Q100 qualified unipolar Hall switch, south pole, 36 mT trip, 15.9 mT release, -40°C to 170°C junction, SOT23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"series":"Automotive, AEC-Q100","has_mpn":"TLE49642","feature_list":"Temperature Compensated","package_type":"Tape & Reel (TR); Cut Tape (CT)","polarization":"South Pole","mounting_type":"Surface Mount","output_signal":"Open Drain","Test Condition":"25°C","product_status":"Active","lifecycle_stage":"eol_hot","timing_function":"Unipolar Switch","supply_voltage_v":"3.0","switching_current_a":"0.0025","output_current_max_a":"0.025","sensing_distance_max_mm":"36mT Trip, 15.9mT Release","Operating Temperature High":"-40°C to 170°C(TJ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.34","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/Infineon-TLE4964_2M-DS-v01_00-en.pdf?fileId=db3a3043397219b60139725f709a006f","sourceUrl":null},"ai":{"faq":[{"question":"How can I order TLE49642MXTMA1 or check stock?","answer":"The TLE49642MXTMA1 is an active Infineon part.

This is a 3 V device; do not connect it directly to a 5 V or 12 V rail without a regulator. The open-drain output can be pulled up to a higher voltage if the pull-up resistor is sized to keep the output current within the 25 mA maximum."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/TLE49642MXTMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/TLE49642MXTMA1 when reusing this data.
