True Zero Speed, Low Jitter, High Accuracy Position Sensor IC

The dual-element Hall IC switches in response to differential magnetic signals created by a ferrous target. Digital processing of the analog signal provides zero-speed performance independent of air gap as well as dynamic adaptation of device performance to the typical operating conditions found in automotive applications.

High-resolution peak detecting DACs are used to set the adaptive switching thresholds of the device. Bounded tracking and switchpoint hysteresis reduce the negative effects of any anomalies in the magnetic signal associated with the targets used in many automotive applications. This sensor IC system is optimized for engine crank applications that utilize targets that possess signature regions.

This device is available in a lead (Pb) free 4-pin SIP package (SG) with a 100% matte tin plated leadframe.
