It is a South Pole polarized latch with an open-drain output rated for 3 V supply voltage. The operating temperature range spans -40°C to 170°C, making it suitable for under-hood automotive, industrial motor drive, and downhole sensor applications where ambient heat exceeds standard 125°C limits. ## Trip thresholds and output drive The magnetic trip point is 10.4 mT (typical at 25°C) with a release point of -10.4 mT, giving a symmetric hysteresis window that prevents output chatter near the switching threshold. The open-drain output can sink up to 25 mA continuous, sufficient to drive a logic input or a small relay coil directly. The quiescent switching current is 2.5 mA at 25°C. Temperature compensation is built in, ensuring the trip point remains stable across the full -40°C to 170°C range rather than drifting with temperature as uncompensated Hall sensors do. ## Active production and sourcing It is a current Infineon catalog part, so BOM positions can be placed without near-term obsolescence risk. The device is — not tape-and-reel — which is typical for sample or low-volume assembly. Confirm your pick-and-place feeder compatibility if using automated placement.","metaTitle":"TLE4961-3K Hall Switch – Infineon, Latch, 3V, Open Drain","metaDescription":"Infineon TLE4961-3K latching hall switch, 3V supply, open-drain output, 10.4 mT trip point.
