SLOS854D May 2014 – March 2018 DRV2605L
The DRV2605L PWM input uses a digital level-shifter. Therefore, as long as the input voltage meets the VIH and VIL levels, the vibration strength remains the same even if the digital levels vary. The DRV2605L device also features power-supply feedback. If the supply voltage drifts over time (because of battery discharge, for example), the vibration strength remains the same as long as enough supply voltage is available to sustain the required output voltage.
