IQS399A
The IQS399A is a ProxFusion® sensing device with an integrated haptics driver capable of driving linear resonant actuator (LRA) motors. A ProxFusion channel event will trigger the haptic driver to allow effective feedback to the user. In addition, the connected system can also inform the user of system-related events via a set of predetermined and configurable sets of haptic patterns. The device offers an I2C mode for haptic and sensor configuration and a standalone mode with GPIO button event output.
