UCC3752DG4

The UCC3752DG4 is an integrated circuit (IC) component designed for driving power MOSFETs and IGBTs in high-frequency applications. It is primarily used in switch-mode power supply (SMPS) and motor control circuits. The UCC3752DG4 incorporates various key features, including: 1. High-Speed Operation: With a propagation delay of only 75 nanoseconds, the UCC3752DG4 enables efficient switching and precise control of power devices in high-frequency applications. 2. Bootstrap Operation: It offers a bootstrap circuit that provides voltage isolation between the low-side gate drive and the high-side gate drive. This feature ensures robust gate driving capability for both high-side and low-side power devices. 3. Output Current Capability: The UCC3752DG4 can deliver a substantial gate current up to 2.5 Amperes, making it suitable for driving power MOSFETs or IGBTs with large gate capacitances. 4. Adaptive Shoot-Through Protection: It includes an adaptive circuit that prevents shoot-through current, which occurs when both MOSFETs in a half-bridge configuration conduct simultaneously. This protection mechanism ensures efficient power conversion and prevents damage to the power semiconductors. 5. Programmable Dead-Time Control: The IC allows for accurate control of dead time, which is essential in preventing any cross-conduction or dead short during PWM signal transitions
