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

26-01-2015 | Texas Instruments | Semiconductors

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.
