IQS7222A
The IQS7222A ProxFusion® IC is a sensor fusion device for applications that require multiple sensing capabilities from a single sensor IC. The sensor is fully I²C compatible, and on-chip calculations enable multiple application options. Various UIs from gestures to power mode switching allow the IC to respond effectively in the intended application with ultra-low power consumption.
