Azoteq IQS6243200DNR

The IQS624 ProxFusion® IC is a versatile capacitive and Hall effect sensor designed for applications that may require any or all of the associated technologies. This combination sensor incorporates Hall effect rotational sensing, along with dual-channel capacitive proximity/touch sensing or single-channel inductive sensing. Two Hall effect sensors calculate the angle of a magnet rotating parallel to the sensor. Fully I²C compatible, the on-chip computation capability enables the IC to directly output the current angle of the magnet without additional calculation.
