SLOS825E December 2012 – April 2018 DRV2605
The user can enter the PWM mode by setting the MODE[2:0] bit to 3 in register 0x01 and by setting the N_PWM_ANALOG bit to 0 in register 0x1D. When in PWM mode, the DRV2605 device accepts PWM data at the IN/TRIG pin. The DRV2605 device drives the actuator continuously in PWM mode until the user sets the device to STANDBY mode or to enter another interface mode. The interpretation of the duty-cycle information varies according to the selected mode of operation. See the Data Formats for Waveform Playback section for details.
