Product Description
1.1
Overview
The TLE4976-2K is a high precision unipolar Hall switch with a two wire,
6mA/14mA current interface in a SMD package. A chopped measurement
principle provides high stability switching thresholds for operating
temperatures between -40°C and 150°C.
1.2
Features
• 3.0V to 26V supply voltage operation
• High sensitivity and high stability of the magnetic switching points
• High resistance to mechanical stress by Active Error Compensation
• Reverse battery protection (-18V)
• Superior temperature stability
• Peak temperatures up to 195°C without damage
• Low jitter (typ. 1µs)
• High ESD performance (± 8kV HBM)
• Digital output signal with current modulation 6 / 14mA
• Unipolar version
• SMD package SC59 (SOT23 compatible)
1.3
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.
