TLE4921-3U Datasheet | Infineon

Features - Advanced performance - High sensitivity - Symmetrical thresholds - High piezo resistivity - Reduced power consumption - South and north pole pre-induction possible - AC coupled - Digital output signal - Two-wire and three-wire configuration possible - Large temperature range - Large airgap - Low cut-off frequency - Protection against overvoltage - Protection against reversed polarity - Output protection against electrical disturbances P-SSO-4-1 Type TLE 4921-3U Marking 21C3U Ordering Code Q67006-A9171 Package P-SSO-4-1 The differential Hall Effect sensor TLE 4921-3U provides a high sensitivity and a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. TLE 4921-3U is particularly suitable for rotational speed detection and timing applications of ferromagnetic toothed wheels such as anti-lock braking systems, transmissions, crankshafts, etc. The integrated circuit (based on Hall effect) provides a digital signal output with frequency proportional to the speed of rotation. Unlike other rotational sensors differential Hall ICs are not influenced by radial vibration within the effective airgap of the sensor and require no external signal processing.
