SLVSEE8B November 2019 – May 2021 DRV8899-Q1
The full-scale current describes the top of the sinusoid current waveform while microstepping. Because the sinusoid amplitude is related to the rms current, the full-scale current is also determined by the thermal considerations of the device. The full-scale current rating is approximately √2 × IRMS.
For the DRV8899-Q1 device, the full-scale current rating is 1 A per bridge.
