Azoteq IQS396 ProxFusion® Sensing Device

Azoteq IQS396 ProxFusion® Sensing Device has a built-in haptics driver for driving Linear Resonant Actuator (LRA) motors. The Azoteq IQS396 provides effective user feedback by triggering the haptic driver during a ProxFusion channel event. The device supports standalone operation with basic configuration via external strap options and an I2C mode with customizable composite waveforms. The I2C mode includes a closed-loop autoresonance algorithm that matches the motor's resonant frequency in real-time. Power consumption is minimized through automatic power management and an ultra-low power mode.
