Smart Haptic Driver Enables HD Haptics on Mobile Devices for Enhanced Gaming, Videos and Music

The CS40L26/CS40L26B is the industry’s leading self-contained haptic driver IC that integrates a DSP and Class D digital boost converter to enable advanced closed-loop control of the actuator, HD enabled haptics and audio generated haptics for use in smartphones, tablets and wearables. Advanced sensor-less velocity control (SVC) provides real-time braking and consistent acceleration of the LRA, plus wider bandwidth and broader frequency range – essential features for gaming UX.
