The UCC27323DR is an advanced dual-channel high-speed low-side gate driver Integrated Circuit (IC) component. It is designed to drive power MOSFETs and IGBTs in high-frequency switching applications such as motor control, power supplies, and active clamping circuits. This IC provides robust and efficient drive for high-side and low-side switches, offering various key features that enhance its performance and reliability.
Key features of UCC27323DR include:
1. Dual-Channel Configurations: The IC consists of two independent high-speed gate drivers, enabling it to drive two separate power switches simultaneously. This feature is beneficial in applications where multiple switches are required to be controlled.
2. Bootstrap Operation: The UCC27323DR implements a bootstrap operation mode, which allows it to efficiently switch the high-side gate driver without requiring an external isolated power supply. This eliminates the need for an additional power source, simplifying the system design and reducing overall component count.
3. Integrated Dynamic Active Miller Clamp: The IC integrates a dynamic active Miller clamp, which helps to prevent the parasitic turn-on of the high-side switch during high dv/dt events. This feature enhances the system's robustness and protects against unintended switching.
4. Adaptive Shoot-Through Protection: UCC27323DR incorporates an adaptive shoot-through protection mechanism that prevents destructive simultaneous conduction of the high-side and low-side switches
