PRODUCTION DATA
The chopping current (ICHOP) is the maximum current driven through either winding. This quantity depends on the sense resistor value (RXISEN).
ICHOP is set by a comparator which compares the voltage across RXISEN to a reference voltage. Note that ICHOP must follow Equation 3 to avoid saturating the motor.
