Flexible haptic control of ERM and LRA actuators over a shared I2C-compatible bus

Designed to provide highly-flexible haptic control of ERM and LRA actuators over a shared I2C-compatible bus, the DRV2605 has been released by Texas Instruments (TI). Saving both costly timer interrupts and hardware pins, the device's control capability relieves the host processor from ever generating pulse-width modulated (PWM) drive signals. The DRV2605 device provides an extensive integrated library over 100 licensed effects from Immersion for ERM and LRA which eliminates the need to design haptics waveforms The DRV2605 device features a trinary-modulated output stage, providing greater efficiency than linear-based output drivers. Its 9-ball WCSP footprint, flexible operation, and low component count make it ideal for portable and touch-enabled vibratory and divers haptic applications, says the company.
