Low side GaN driver with 60MHz/1ns speed

Texas Instruments’ LMG1020 device is a single, low-side driver designed for driving GaN FETs and logic-level MOSFETs in high-speed applications including 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 2.5ns and minimum pulse width of 1ns. 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 undervoltage lockout (UVLO) and overtemperature protection (OTP) in the event of overload or fault conditions. 0.8mm × 1.2mm WCSP package of LMG1020 minimises gate loop inductance and maximises power density in high-frequency applications.
