Additional Details

The CS35L20-CWZR is designed to drive a variety of haptic actuators, including linear resonant actuators (LRAs) and eccentric rotating mass (ERM) motors. It features advanced waveform generation capabilities, allowing for the creation of complex and nuanced tactile effects. The integrated boost converter provides the necessary voltage to drive the actuators, ensuring strong and consistent haptic output. The low latency response ensures that the haptic feedback is synchronized with the user's actions, creating a more immersive and realistic experience. The I2C control interface allows for easy configuration and control of the driver's parameters, such as waveform shape, amplitude, and frequency. The adaptive resonance tracking feature optimizes the haptic performance by automatically adjusting the drive frequency to match the resonant frequency of the actuator. The automatic gain control (AGC) maintains a consistent haptic output, even with variations in actuator characteristics or battery voltage. The over-current and over-temperature protection features ensure reliable operation and prevent damage to the driver and actuator.
