Texas Instruments UCC5304 Isolated Single-Channel Gate Driver

Texas Instruments UCC5304 Isolated Single-Channel Gate Driver includes 4A peak-source and 6A peak-sink current. It is designed to drive power MOSFETs and GaNFETs in PFC, Isolated AC/DC, DC/DC, and synchronous rectification applications. The device has fast switching performance and robust ground bounce protection through greater than 100V/ns common-mode transient immunity (CMTI). The Texas Instruments UCC5304 is available in an 8.5mm SOIC-8 (DWV) package and can support isolation voltage up to 5kVRMS. Compared to an optocoupler, the UCC5304 family has lower part-to-part skew, lower propagation delay, higher operating temperature, and higher CMTI.

Protection features include IN pin rejects input transient shorter than 5ns, both input and output can withstand –2V spikes for 200ns, and both supplies have undervoltage lockout (UVLO). The device also features active pull-down protection that clamps the output below 2.1V when unpowered or floated. With these features, this device enables high efficiency, high power density, and robustness in a wide variety of power applications.
