Texas Instruments LMG1020 Low-Side GaN Driver
Texas Instruments LMG1020 Low-Side GaN Driver is a single, low-side driver designed for driving GaN FETs and logic-level MOSFETs in high-speed applications. These applications include LiDAR, time-of-flight, facial recognition, and any power converters involving low-side drivers. The design simplicity of the LMG1020 enables extremely fast propagation delays of 2.5 nanoseconds and minimum pulse width of 1 nanosecond. The drive strength is independently adjustable for the pull-up and pull-down edges by connecting external resistors between the gate and OUTH and OUTL, respectively. The driver features under voltage lockout (UVLO) and over-temperature protection (OTP) in the event of overload or fault conditions.Features
