IQS7222E

The IQS7222E 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 allows the IC to respond effectively in the intended application with ultra-low power consumption.
