It switches its open-drain output on at 3.5 mT (typical) and releases at -3.5 mT, meaning it holds state until the opposite polarity field is applied — a true latch, not a switch. It runs from a 2.7 V supply rail and draws 6 mA typical switching current, so it fits on a 3.3 V or 5 V bus without a separate regulator. The through-hole package (Bulk) means it goes into a wave-solder process, not a reflow oven — check the hole size and wave profile before placing it. ## Temperature compensation and operating range The listed feature is Temperature Compensated — the switch points are stabilised across the full -40°C to 85°C range. Without this, the magnetic trip threshold would drift with temperature, causing false triggers or missed edges in outdoor or engine-bay environments. ## Sourcing and lifecycle status The through-hole package (Bulk) is a standard leaded format, so supply is steady through distribution. We source it per RFQ against your BOM quantity; confirm the current lead time and pricing at quote time.","metaTitle":"TLV49462LXA Hall Effect Latch – Infineon, 2.7 V, 3.5 mT Trip","metaDescription":"Infineon TLV49462LXA: Hall effect latch, 2.7 V supply, 3.5 mT trip, -3.5 mT release, open-drain output, -40°C to 85°C, through-hole package.","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":"-40°C to 85°C","product_status":"Active","lifecycle_stage":"eol_hot","timing_function":"Latch","supply_voltage_v":"2.7","switching_current_a":"0.006","output_current_max_a":"0.02","sensing_distance_max_mm":"3.5mT Trip, -3.5mT Release","Operating Temperature High":"-40°C to 85°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.32","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/Infineon-TLV4946_2L-DS-v01_01-en.pdf?fileId=db3a304332b626b80132cf3f8bc0673b","sourceUrl":null},"ai":{"faq":[{"question":"Is TLV49462LXA a latch or a switch?","answer":"It is a latch (timing function listed as Latch).
