The UCC21220 and UCC21220A devices are basic and functional isolated dual-channel gate drivers with 4-A peak-source and 6-A peak-sink current. They are designed to drive power MOSFETs and GaNFETs in PFC, Isolated DC/DC, and synchronous rectification applications, with fast switching performance and robust ground bounce protection through greater than 100-V/ns common-mode transient immunity (CMTI).These devices can be configured as two low-side drivers, two high-side drivers, or half-bridge drivers. Two outputs can be paralleled to form a single driver which doubles the drive strength for heavy load conditions due to the best-in-class delay matching performance.Protection features include: DIS pin shuts down both outputs simultaneously when it is set high; INA/B pin rejects input transient shorter than 5-ns; both inputs and outputs can withstand –2-V spikes for 200-ns, all supplies have undervoltage lockout (UVLO), and active pull down protection clamps the output below 2.1-V when unpowered or floated.With these features, these devices enable high efficiency, high power density, and robustness in a wide variety of power applications.
