Product details

Unipolar Hall switch with temperature compensation

The TLE4976-2K is a unipolar Hall-effect switch from Infineon, designed for magnetic field detection with a south-pole activation polarity. 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.

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. 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.

— 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.

Frequently asked questions

What is the difference between TLE4976 and TLE4976-2K?

The -2K suffix on the TLE4976-2K indicates a specific ordering code variant — typically package or packing option. The core Hall switch function (unipolar, temperature compensated, 18 mT trip / 5 mT release) is identical across the TLE4976 family. Confirm the exact suffix against your BOM to avoid a footprint mismatch.
