(1)Patent pending control algorithm

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.

The DRV2604 device includes enough integrated RAM to allow the user to pre-load over 100 customized waveforms. These waveforms can be instantly played back through I2C or optionally triggered through a hardware trigger pin. Additionally, the real-time playback mode allows the host processor to bypass the library playback engine and play waveforms directly from the host through I2C.

The DRV2604 device also contains a smart-loop architecture, which allows effortless auto resonant drive for LRA as well as feedback-optimized ERM drive. This feedback gives automatic overdrive and braking, which creates a simplified input waveform paradigm as well as reliable motor control and consistent motor performance.

The DRV2604 device features a trinary-modulated output stage, providing greater efficiency than linear-based output drivers. The 9-ball WCSP footprint, flexible operation, and low component count make the DRV2604 device the ideal choice for portable and touch-enabled vibratory and haptic applications.
