Preliminary
LINEAR INTEGRATED CIRCUIT
DYNAMIC DIFFERENTIAL HALL
EFFECT SENSOR IC WITH
DIGITAL SIGNAL OUTPUT
 DESCRIPTION
The differential Hall Effect sensor UTC UH4921 provides a
superior stability and a high sensitivity over temperature and
symmetrical thresholds in order to achieve a stable duty cycle. The
integrated circuit 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.
UTC UH4921 is particularly suitable for rotational speed
detection and timing applications of ferromagnetic toothed wheels
such as anti-lock braking systems, transmissions, crankshafts, etc.
