The current flowing through the high-side and low-side drivers is monitored to ensure that the motor lead is not shorted to supply or ground. If a short is detected, the full-bridge outputs are turned off, flag nFAULT is driven low, and a 1.2-ms fault timer is started. After this 1.2-ms period, tOCP , the device is then allowed to follow the input commands and another turnon is attempted (nFAULT becomes high again during this attempt). If there is still a fault condition, the cycle repeats. If after tOCP expires it is determined the short condition is not present, normal operation resumes and nFAULT is deasserted.
