Haptics + Sensing = Rich User Experiences
By Mat Dirjish
Haptics, sometimes defined as “the use of technology that stimulates the senses of touch and motion in remote-control operations”, is finding its way into a greater number of applications. With that, the demand for ever-better end-user experiences is on the rise as well. Cirrus Logic says its haptic products and haptic-feedback technology enable sleeker, more robust end products with fewer mechanical controls for more responsive and immersive user experiences.
On that note, the company unveils its CS40L25 family of haptics devices that includes:
- The CS40L25-CWZR and CS40L25B-CWZR ICs in 30-ball WLCSP packages for mobile and portable applications (now shipping in volume).
- The CS40L25B-CNZR commercial-grade 32-pin QFN chip for PC/laptop and other general market applications (currently sampling).
- The CS40L25B-DNZ AEC-Q100 automotive-qualified version in a 32-pin QFN package with wettable flanks for infotainment applications such as touch buttons and touch screens (currently sampling).
The devices have several features in common. For example, they integrate a haptic driver, digital-signal processor, and a boost converter. They are resonance-aware, capable of driving high-performance linear resonant actuators (LRAs) and voice coil motors (VCMs), and support unique, pre-stored haptic waveforms.
The family also boasts ultra-low latency that provides real-time control of the haptic motor and include closed-loop algorithms to maximize LRA effectiveness and enable crisp, clear, and consistent haptics.
