ProxFusion™ Series

IQS624 Datasheet

Combination sensor including: Hall-effect rotation sensing, along with dual-channel

capactive proximity/touch sensing, or single-channel inductive sensing.

The IQS624 ProxFusion™ IC is a multifunctional capacitive and Hall-effect sensor designed for

applications where any or all of the technologies may be required. The two Hall-effect sensors

calculate the angle of a magnet rotating parallel with the sensor. The sensor is fully I²C compatible

and on-chip calculations enable the IC to stream the current angle of the magnet without extra

calculations.
