LMG1020YFFR

The LMG1020 is a single-channel low-side driver designed to drive GaN FETs and logic-level MOSFETs in high-speed applications including LiDAR, time-of-flight, facial recognition, and any power converter involving a low-side driver. The LMG1020 features a minimalist design that achieves an ultra-fast propagation delay of 2.5 ns and a minimum pulse width of 1 ns. Drive strength for the pull-up and pull-down edges can be independently adjusted by connecting external resistors between the gate and OUTH and OUTL, respectively. The driver provides UVLO and OTP under overload or fault conditions. The LMG1020's 0.8mm×1.2mm WCSP package minimizes gate loop inductance and maximizes high-frequency power density requirements.
