TLE4921-5U Description

Short technical summary and product information.

The Infineon Technologies TLE4921-5U is a dynamic differential Hall effect sensor IC designed for high sensitivity and superior stability over temperature. It provides symmetrical thresholds, ensuring a stable duty cycle, making it particularly suitable for rotational speed detection and timing applications involving ferromagnetic toothed wheels.

 

This integrated circuit offers a digital output signal that is frequency-proportional to the speed of rotation. Unlike other rotational sensors, differential Hall ICs are not influenced by radial vibration within the effective airgap and require no external signal processing. The TLE4921-5U is available in a PG-SSO-4-1 package and supports both two-wire and three-wire configurations.

 

Key features include advanced performance, high piezo resistivity, reduced power consumption, and a large temperature range. It also offers protection against overvoltage, reversed polarity, and electrical disturbances, contributing to its reliability in demanding applications such as anti-lock braking systems, transmissions, and crankshafts.
