It operates from a 2.7 V supply rail, allowing direct connection to 3.3 V or 2.8 V automotive sensor buses without an intermediate regulator. The magnetic switch points are 13.9 mT (trip) and 4.7 mT (release), with a South Pole activation — this simplifies magnet polarity selection in assembly and reduces false triggers from stray North Pole fields. ## Magnetic switch points and output drive Output is open-drain, rated for 20 mA continuous sink current — sufficient to drive a logic input or a low-power LED indicator directly. The switching current is 6 mA typical. Compared to the sibling TLI49462KHTSA1, which has a 19.2 mT trip and -19.2 mT release (bipolar latch), the TLI4906KHTSA1 is a unipolar switch with a wider hysteresis (9.2 mT vs 38.4 mT) — better suited for simple presence/absence detection where the magnet passes once per cycle. ## Active production and package availability It ships in Tape & Reel (TR) or Cut Tape (CT) for the SC59 SMD package. The -40°C to 125°C operating temperature range covers under-hood and cabin automotive environments. Temperature compensation is built in to maintain stable switch points across the range. ## Sourcing and cross-reference note The TLI49611MXTSA1 is a latch-type device with 3.5 mT / -3.5 mT trip points and a 3.0 V supply, suitable for applications needing direction detection.","metaTitle":"TLI4906KHTSA1 – Infineon Automotive AEC-Q100 Unipolar Hall","metaDescription":"Infineon TLI4906KHTSA1 unipolar Hall switch, AEC-Q100 qualified, 2.7 V supply, 13.9 mT trip / 4.7 mT release, SC59 SMD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"series":"Automotive, AEC-Q100","has_mpn":"TLI4906","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":"-40°C to 125°C","product_status":"Active","lifecycle_stage":"eol_hot","timing_function":"Unipolar Switch","supply_voltage_v":"2.7","switching_current_a":"0.006","output_current_max_a":"0.02","sensing_distance_max_mm":"13.9mT Trip, 4.7mT Release","Operating Temperature High":"-40°C to 125°C(TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.36","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/74a6020fbb4ecaa96b90c051ff8174bd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TLI4906KHTSA1 a direct replacement for TLI4906?","answer":"The TLI4906KHTSA1 shares the same base MPN TLI4906 and is the surface-mount SC59 variant of the through-hole TLI4906L.
