New Low-Side GaN Driver introduced, ideal for High-Speed LiDAR and TOF Applications


Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the LMG1020 gallium nitride (GaN) driver from Texas Instruments. The single, low-side driver enables efficient, high-performance designs in speed-critical applications such as LiDAR, time-of-flight laser drivers, facial recognition, augmented reality, and class E wireless chargers.

The Texas Instruments LMG1020 low-side GAN driver, available from Mouser Electronics, drives GaN FETs and logic-level MOFSETs, enabling propagation delays of just 2.5 nanoseconds and minimum pulse width of 1 nanosecond. The device’s drive strength is independently adjustable for pull-up and pull-down edges by connecting external resistors between the gate and OUTH and OUTL, respectively. The robust LMG1020 driver features over-temperature protection and under-voltage lockout to guard against overload and fault conditions, plus common-mode transient immunity of more than 300V/ns, delivering industry-leading system-noise immunity.

The LMG1020 is housed in a 0.8 mm × 1.2 mm WCSP package, which minimizes gate loop inductance and maximizes power density in high-frequency applications. The miniscule size allows designers to reduce component count and decrease power supply size by up to 80 percent. The LMG1020 driver features an adjustable dead-time control feature to provide improved efficiency for applications such as DC-DC converters, Class D audio amplifiers, and motor drives.
