PRINCIPLES OF OPERATION
current limit/over-current shutdown
Referring to Figure 15, two comparators monitor the voltage drop across an external current sensing resistor,
R(SENSE).Thesensedvoltage,V(SENSE),isthencomparedagainsttwoVCC referredvoltages,VLandV(OCSD).
When V(SENSE) exceeds VL, the ILIM comparator outputs a high level. When V(SENSE) exceeds V(OCSD), the
OCSD comparator also outputs a high level. The combination of these two comparator outputs is then used in
conjunction with a deglitch or blanking timer to discriminate between a high di/dt, short-duration current spike.
This spike is commonly caused by reverse recover time (trr) current at the start of each PWM cycle and a portion
of the current waveform with lower di/dt. The lower di/dt is controlled by the L/R time constant of the motor
winding (see Figure 16). A comparator is also used to detect over current conditions caused by a shorted-load
or shorted phase-winding to GND (see Figure 17).
