Precautions for Application
Test result of short between pins Test condition : VCC = 30 V DC power supply ( 30 V , 5 A )
: No destruction of IC for pins short for 3secs. : Destruction of IC for pins short for 1second. After destruction, continuous supply of VCC may cause IC package to crack. To prevent this problem, insert resistance ( 2 to 3 ) for over current limited in VCC line.
