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.
Features
 Hall effect angle sensor:
o On-chip Hall plates
o 360° Output
o 1° Resolution, calculated on chip
o Relative rotation angle.
o Detect movement and the direction of
movement.
o Raw data: can be used to calculate
degrees on external processor.
o Operational range 10mT – 100mT
o No external components required
 Partial auto calibration:
o Continuous auto-calibration,
compensation for wear or small
displacements of the sensor or magnet.
o Flexible gain control
o Automatic Tuning Implementation (ATI)
– Performance enhancement (10 bit).
 Capacitive sensing
o Full auto-tuning with adjustable
sensitivity
o 2pF to 200pF external capacitive load
capability
Inductive sensing
o Only external sense
coil required (PCB
trace)
 Multiple integrated UI
o Proximity / Touch
o Proximity wake-up
o Event mode
o QRD (Quick release detection)
o Wake Hall sensing on proximity
 Minimal external components
 Standard I²C interface
 Optional RDY indication for event
operation
 Low power consumption:
