Its open collector output switches low when the field exceeds the 18 mT trip point and releases at 5 mT, providing a clean digital signal to a downstream controller or PLC input. Temperature compensation stabilises the magnetic switch points across the full -40°C to 150°C range, so the air-gap threshold does not drift with engine bay heat or cold-soak — a common failure point in uncompensated Hall sensors. ## Supply and output ratings for BOM fit Runs on a 3.8 V supply rail — compatible with 3.3 V or 5 V logic families via a pull-up resistor on the open collector output. The output sinks up to 100 mA continuous, enough to drive a small relay or optocoupler directly without a buffer transistor. Switching current is 8 mA typical — the device itself draws very little, so the supply can share a lightly loaded 3.3 V rail without thermal concern. ## Active production and sourcing — not tape-and-reel, so plan for manual or tube-fed pick-and-place if your line expects reeled parts. Surface-mount package suits standard reflow profiles.","metaTitle":"TLE4976-2K Active, Temperature Compensated","metaDescription":"Infineon TLE4976-2K unipolar Hall switch, 3.8 V supply, open collector output, 18 mT trip / 5 mT release, -40°C to 150°C.
