SLVSD39D October 2015 – March 2020 DRV8885
PRODUCTION DATA.
The full-scale current describes the top of the sinusoid current waveform while microstepping. Since the sineusoid amplitude is related to the rms current, the full-scale current is also determined by the thermal considerations of the IC. The full-scale current rating is approximately √2 × Irms. The full-scale current is set by VREF, the sense resistor, and Torque DAC when configuring the DRV8885, see Current Regulation for details. For the DRV8885, the full-scale current rating is 1.5 A per bridge.
