Power-On Time

After the VCC voltage is applied, the DRV5055 requires a short initialization time before the output is set. The parameter tON describes the time from when VCC crosses 3 V until OUT is within 5% of VQ, with 0 mT applied and no load attached to OUT. Figure 17 shows this timing diagram.
