Texas Instruments  UCC27611DRVT

The UCC27611 is a single-channel, high-speed, gate driver optimized for 5-V drive,specifically addressing enhancement mode GaN FETs. The drive voltage VREF is precisely controlledby internal linear regulator to 5 V. The UCC27611 offers asymmetrical rail-to-rail peak currentdrive capability with 4-A source and 6-A sink. Split output configuration allows individual turnonand turnoff time optimization depending on FET. Package and pinout with minimum parasiticinductances reduce the rise and fall time and limit the ringing. Additionally, the shortpropagation delay with minimized tolerances and variations allows efficient operation at highfrequencies. The 1-Ω and 0.35-Ω resistance boosts immunity to hard switching with high slew rate dVand dt.

The independence from VDD input signal thresholds ensure TTL and CMOS low-voltage logiccompatibility. For safety reason, when the input pins are in a floating condition, the internalinput pullup and pulldown resistors hold the output LOW. Internal circuitry on VREF pin provides anundervoltage lockout function that holds output LOW until VREF supply voltage is within operatingrange. UCC27611 is offered in a small 2.00 mm × 2.00 mm SON-6 package (DRV) with exposed thermaland ground pad that improves the package power-handling capability. The UCC27611 operates over widetemperature range from –40°C to 140°C.
