It is required to use a resistor with low internalinductance because high-frequency switching current willflow through the shunt resistors, RSx. In addition, choosea resistor with allowable power dissipation according toyour application.When you connect a CR filter (i.e., a pair of a filterresistor, RO, and a filter capacitor, CO) to the OCP pincare should be taken in setting the time constants of ROand CO. The larger the time constant, the longer the timethat the OCP pin voltage rises to VTRIP. And this maycause permanent damage to the transistors. Consequently,a propagation delay of the IC must be taken into accountwhen you determine the time constants. For RO and CO,their time constants must be set to the values listed inTable 12-3. And place CO as close as possible to the ICwith minimizing a trace length between the OCP andCOMx pins.Note that overcurrents are undetectable when one ormore of the U, V/V1/V2, and W1/W2 pins or their tracesare shorted to ground (ground fault). In case any of thesepins falls into a state of ground fault, the output transistorsmay be destroyed.
