IQS390
Azoteq IQS390 Haptics Driver Azoteq IQS390 Haptics Driver is designed for Linear Resonant Actuator (LRA) motors. The Azoteq IQS390 supports I2C mode with configurable composite waveforms and a closed-loop autoresonance algorithm that dynamically adjusts to the motor's resonant frequency in real time. It also offers a PWM mode that accepts an external PWM signal and motor drive direction. Both modes incorporate automatic power management and an ultra-low power mode for efficient operation.
