IQS624/5 Eval Kit 4

The IQS624 and IQS625 ProxFusion® IC’s are multifunctional capacitive, inductive and Hall effect sensors designed for applications where any or all of the technologies may be required. The Hall effect sensors calculate the angle of a magnet rotating parallel or perpendicular with the IC, creating a contactless 360° rotation sensor. The IQS624 and IQS625 are ultra-low power Hall effect rotation sensors. These sensors are fully I2C compatible and on-chip iqs625 ev04calculations enable the IC’s to stream the current angle/interval of the magnet without extra calculations.
