It switches on when a north pole field exceeds 2.25 mT and releases when the south pole field drops below -2.25 mT, making it suitable for position and speed sensing in brushless DC motors, transmission gear detection, and valve position feedback. The open-drain output sinks up to 25 mA, and the device operates from a 3 V to 32 V supply, covering 5 V logic, 12 V automotive battery, and 24 V industrial buses without an external regulator. ## Temperature range and qualification — built for under-hood and industrial Rated for a junction temperature range of -40°C to 170°C, this part handles the thermal extremes found in engine bays, exhaust-adjacent sensors, and high-temperature industrial enclosures. AEC-Q100 qualification confirms it meets automotive reliability standards for stress, lifetime, and quality — a requirement for Tier-1 automotive programs and a strong indicator for long-life industrial designs that want a proven silicon process. ## Package and footprint — hand-solderable SOT-23-3 Supplied in a PG-SOT23-3-15 package (industry-standard SOT-23-3 footprint), this is a three-pin device that hobbyists and rework techs can hand-solder with a fine-tip iron. The small body saves board space in compact sensor modules. Available in Tape & Reel for automated pick-and-place or Cut Tape for prototyping. ## Sourcing and lifecycle — active production, no LTB risk For current pricing and availability, submit an RFQ — we source through independent distribution and confirm both at quote time.","metaTitle":"TLE49681MXTSA1 Hall Effect Bipolar Switch, AEC-Q100","metaDescription":"Infineon TLE49681MXTSA1 automotive-grade bipolar Hall switch.
