UCC5304 Single-Channel Isolated Gate Driver

Texas Instruments' UCC5304 is an isolated single-channel gate driver with 4 A peak-source and 6 A peak-sink current. This driver is designed to drive power MOSFETs and GaN FETs in PFC, isolated AC/DC, DC/DC, and synchronous rectification applications. The UCC5304 offers fast switching performance and robust ground bounce protection through common-mode transient immunity (CMTI) of greater than 100 V/ns. The driver is available in an 8.5 mm SOIC-8 (DWV) package and can support isolation voltage up to 5 kV_RMS.

Compared to an optocoupler, the UCC5304 gate driver has lower part-to-part skew, lower propagation delay, wider operating temperature range, and higher CMTI. The IN pin rejects input transients shorter than 5 ns, the input and output can withstand -2 V spikes for 200 ns, both supplies have undervoltage lockout (UVLO), and active pull-down protection clamps the output below 2.1 V when unpowered or floated. These protection features enable high efficiency, high power density, and robustness in a wide variety of power applications.
