DRV2604 Description
The DRV2604 device is designed to provide extremely flexible haptic control of ERM and LRA actuators over a shared I2C patible bus. This control relieves the host processor from ever generating pulse-width modulated (PWM) drive signals, saving both costly timer interrupts and SDA SCL EN IN/TRIG REG 2 I C I/F REG Control and playback engine Back-EMF detection Gate drive hardware pins.
