IQS624

IQ Switch® 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° Absolute 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 Wide operational range 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 DFN10 WLCSP-9 Representations only, not actual markings o Wake Hall sensing ...
