Part Number:DRV8702D-Q1
Does the level of Vdrain have an effect on sensitivity of internal current regulation amplifier ?
For zero current and 5.5<Vdrain<12V, Voltage at SO pin is 480mV.
For zero current and Vdrain<5V, Voltage at SO pin is 200mV less.
Motor not spinning at Vdrain<5V, but value will be used for 0A reference.
Please explain relationship Vdrain - SO Voltage for this range of Vdrain.
