Overview

DA7280 LRA/ERM Haptic Driver with Multiple Input Triggers, Integrated Waveform Memory and Wideband Support General Description DA7280 is a linear resonant actuator (LRA) and eccentric rotating mass (ERM) haptic driver offering automatic closed-loop LRA resonant frequency tracking.
The feature guarantees consistency across LRA production tolerances, operating temperature, aging, and mechanical coupling.
DA7280 offers wideband operation that fully utilizes the capabilities of newer wideband and multi-directional LRAs.
The differential output drive architecture and continuous actuator motion sensing enable efficient, calibration-free playback and minimize software complexity.
Featuring wake-up on General Purpose Input (GPI) sequence triggers and/or I2C activity, DA7280 automatically returns to a low quiescent current state (typically 0.
36 µA) between playbacks.
At only 20 % of the idle current of the nearest alternative solution, DA7280 significantly extends battery life in mobile system...
