Latching hall switch for high-temperature sensing
The TLE4961-3K is a latching hall-effect switch from Infineon, meaning it toggles its output state on alternating magnetic poles and holds that state until the opposite pole is applied. It is a South Pole polarized latch with an open-drain output rated for 3 V supply voltage.
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 quiescent switching current is 2.5 mA at 25°C.
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.
