Product Description

1.1

Overview

The TLE4976-1K and TLE4976L are high precision unipolar Hall switches

with a two wire, 6mA/14mA current interface in a SMD or leaded package.

A chopped measurement principle provides high stability switching

thresholds for operating temperatures between -40°C and 150°C.

Target Applications

The sensor targets all applications where a high precision unipolar magnetic switch is required (e.g. position

sensing). Due to the current interface the number of wires required in the application is minimized thus saving

costs and increasing reliability. This is specially helpful in all applications where the microcontroller is not on the

same PCB as the Hall switch but in some distance.
