9.2.1.3.1.1.2 Hardware Stall Threshold Selection

The voltage on the VREF pin selects ITRIP threshold which sets the current level for stall detection and current regulation. This threshold should be chosen such that ITRIP is less than the stall current of the motor when current regulation is not used. It should also be set low enough to account for variation in the stall current due to changes in the motor supply voltage, VVM, and temperature. Section 8.4.2.2 and Section 8.4.3 provide more details for configuring the voltage on the VREF pin.
