8.3.5 Short Circuit Clamping

During short circuit condition, the miller capacitance can cause a current sinking to the OUTH/OUTL pin due to the high dV/dt and boost the OUTH/OUTL voltage. The short circuit clamping feature of UCC21710-Q1 can clamp the OUTH/OUTL pin voltage to be slightly higher than VDD, which can protect the power semiconductors from a gate-source and gate-emitter overvoltage breakdown. This feature is realized by an internal diode from the OUTH/OUTL to VDD.
