The UCC27611DRVT is a single-channel high-speed Gate Driver optimized for 5V drive, specifically addressing enhancement mode GaN FETs. The drive voltage VREF is precisely controlled by internal linear regulator to 5V. It offers asymmetrical rail-to-rail peak current drive capability with 4A source and 6A sink. Split output configuration allows individual turn-ON and turnoff time optimization depending on FET. Additionally, the short propagation delay with minimized tolerances and variations allows efficient operation at high frequencies. The 1 and 0.35R resistance boosts immunity to hard switching with high slew rate dV and dt. The independence from VDD input signal thresholds ensure TTL and CMOS low-voltage logic compatibility. For safety reason, when the input pins are in a floating condition, the internal input pull-up and pull down resistors hold the output low.
