3 Description
The DRV2605 device is designed to provide
extremely-flexible haptic control of ERM and LRA
actuators over a shared I
2
C-compatible bus. This
control relieves the host processor from ever
generating pulse-width modulated (PWM) drive
signals, saving both costly timer interrupts and
hardware pins.
