ABSTRACT
ThePowerDriveProtectionInterrupt(PDPINT)pinisasafetyfeaturethatisbuiltintoall
TMS320C24xEDSPs.Thisfeatureprotectstheelectricaldrivefromdamageduetoany
electrical,mechanicalorthermalabnormalities.Whenthispinisdrivenlowexternally,allthe
PWMoutputsareputinahighimpedancestate,therebyprotectingtheelectricaldrivefrom
furtherdamage.AproperunderstandingofthefunctioningandlimitationsofthePDPINT
moduleisnecessarytorealizethebenefitsofthisfeature.
