SLOS824B – DECEMBER 2012 – REVISED DECEMBER 2015 DRV2604 Haptic Driver for ERM and LRA With Internal Memory
and Smart-Loop Architecture
Check for Samples: DRV2604 1 Features 3 Description The DRV2604 device is designed to provide
extremely flexible haptic control of ERM and LRA
actuators over a shared I2C 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. 1 (1) Flexible Haptic/Vibra Driver
