Overview

The TLV4976-1K 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 85°C.

Features

• 3.0V to 18V 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

• Low jitter (typ. 1µs)

• High ESD performance (± 4kV HBM)

• Digital output signal with current modulation 6 / 14mA

• Unipolar version

• SMD package SC59 (SOT23 compatible), lead free and halogen free

• For industrial and consumer applications, not qualified for automotive applications

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.
