图1DRV2605L内部结构图

The DRV2605L device is a low-voltage haptic driver that relies on the back-EMF produced by an actuator to provide a closed-loop system that offers extremely flexible control of LRA and ERM actuators over a shared I2Ccompatible bus or PWM input signal. This schema helps improve actuator performance in terms of acceleration consistency, start time, and brake time.

The DRV2605L device offers a licensed version of TouchSense 2200 software from Immersion which eliminates the need to design haptic waveforms because the software includes over 100 licensed effects (6 ERM libraries and 1 LRA library) and audio-to-vibe features.
