Working Principles

UCC27323DGNG4 operates by receiving an input signal (IN) and generating complementary gate drive signals for the high-side (HO) and low-side (LO) power devices. The bootstrap supply voltage (VS) and high-side floating supply voltage (VB) provide the necessary biasing for the gate drivers. The device incorporates shoot-through protection to prevent simultaneous conduction of the high-side and low-side drivers, reducing the risk of short circuits. Additionally, thermal shutdown protection ensures safe operation by disabling the outputs when the temperature exceeds a specified threshold.
