DA7280 Ultra-Low-Power Wideband Haptic Driver for ERM and LRA Actuators The DA7280 high definition (HD) haptic driver combines custom drive sequences (at up to 1 kHz) for HD haptic effects, along with resonant frequency tracking for driving both LRA and ERM actuators. It provides superior click/vibration effects in smartphone, gaming, and wearables applications. The DA7280 is also ideal for use in industrial applications such as touch screen banking ATEs and in automotive areas such as steering wheel driver feedback. The DA7280s very low idle state current consumption maximizes the battery life of haptic driver applications, which spend the majority of their time in standby/idle modes. The current consumption of the DA7280 is 80 % lower than the nearest alternative solution. Multiple general purpose trigger inputs and a low-latency ensure highly reactive triggering of haptic 2 sequences from button, screen, or I C inputs. This is ideal for Android systems with a sensor hub and an application processor. The application processor can remain in deep sleep and the sensor hub can trigger up to six haptics events directly. Then, in active modes, the application processor can trigger 2 or stream complex sequences using I C. This flexibility allows for complex streaming of sequences in active modes, and low-latency tact switch replacement for effects in sleep modes. www.dialog-semiconductor.com Unlike current alternative solutions, sequence storage in the device is achieved using frequency, amplitude and duration snippets, allowing complex, on and off resonant effects to be stored, played, or streamed. Ease of use and flexibility are combined for both simple and complex systems. The DA7280 comes in both WLCSP packaging for size critical consumer products and in QFN packaging for customers looking to lower PCB assembly costs.
