The operate point is 3.5 mT; the release point is -3.5 mT. This makes it suitable for brushless-DC motor commutation, position sensing, and speed detection where a rotating magnet passes the sensor. Output is open drain, rated for 25 mA continuous sink current. The 3 V supply rail aligns with low-voltage 3.3 V logic systems commonly used in industrial control boards. ## Temperature range and environment fit Rated for -40°C to 125°C ambient, the TLV4961-1TB can be placed in engine-bay, motor-drive, or outdoor telecom enclosures where the ambient temperature exceeds the 85°C ceiling of commercial-grade sensors. The temperature-compensated feature stabilises the magnetic thresholds across this span, so the operate/release window does not drift with the heat from the motor windings. ## Package and mounting for the BOM as a through-hole device. The through-hole footprint is straightforward to hand-assemble or wave-solder; no reflow profile to qualify. The south-pole polarisation means the sensor responds to the south face of the magnet — confirm the magnet orientation in the assembly before committing the BOM position. ## Lifecycle and sourcing reality This is a current-production part from a major supplier, so allocation risk is low under normal market conditions. Sourced per RFQ against the BOM quantity; no stock-holding claim or firm lead time published here.","metaTitle":"TLV4961-1TB Hall Switch – Infineon, Latch, 3 V, Open Drain","metaDescription":"Infineon TLV4961-1TB Hall Switch: latching bipolar switch, 3 V supply, open-drain output, 3.5 mT operate / -3.5 mT release, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"feature_list":"Temperature Compensated","package_type":"Bulk","polarization":"South Pole","mounting_type":"Through Hole","output_signal":"Open Drain","Test Condition":"25°C","product_status":"Active","lifecycle_stage":"eol_hot","timing_function":"Latch, Bipolar Switch","supply_voltage_v":"3.0","switching_current_a":"0.0025","output_current_max_a":"0.025","sensing_distance_max_mm":"3.5mT Trip, -3.5mT Release","Operating Temperature High":"-40°C to 125°C(TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.30","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e73b460eb9067c609a95e745dd65d042.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TLV4961-1TB a latching hall switch?","answer":"Yes, it is a latching bipolar switch. It latches the output when a south pole of sufficient flux is applied and releases only when a north pole of opposite polarity is sensed. This is distinct from a unipolar switch, which turns on with one pole and off when the field is removed."},{"question":"Can TLV4961-1TB be used as a replacement for TLV4961-2TB?","answer":"The TLV4961-1TB and TLV4961-2TB are both latching bipolar Hall switches from the same Infineon family, but the evidence does not provide the specific threshold differences between the two. Confirm the operate/release points of the 2TB variant against the 3.5 mT / -3.5 mT values of the 1TB before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/TLV4961-1TB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/TLV4961-1TB when reusing this data.
