简介：The IQS397 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. Standalone operation allows basic configuration via external strap options. The device also offers an I2C mode featuring configurable composite waveforms. The I2C mode features a closed-loop autoresonance algorithm. The autoresonance algorithm matches the resonant frequency of the driven motor in real time. Power consumption is optimised by automatic power mode management and an ultra-low power mode.
