High-efficiency design for speed-critical applications
Propagation delay time 2.5ns, minimum pulse width 1ns
Overtemperature protection and undervoltage lockout features
Mouser Electronics supplies the gallium nitride (GaN) driver LMG1020 from Texas Instruments. The LMG1020, a single low-side driver, enables high-efficiency, high-performance designs in speed-critical applications such as LiDAR, ToF laser drivers, facial recognition, augmented reality, and Class E wireless chargers.

The TI LMG1020 low-side GaN driver supplied by Mouser drives GaN FETs and logic-level MOSFETs with a propagation delay time of just 2.5ns and a minimum pulse width of 1ns.

By connecting external resistors between gate and OUTH, and between gate and OUTL respectively, the drive strength can be individually adjusted to the pull-up and pull-down edges.

The LMG1020 driver features overtemperature protection and undervoltage lockout to protect against overload and fault conditions. It has common-mode transient immunity greater than 300V/ns and provides a high level of system noise immunity.

The LMG1020 is produced in a 0.8×1.2mm WCSP package to minimize gate loop parasitic inductance and maximize power density in high-frequency applications. As a compact device, designers can reduce component count and reduce power supply requirements by up to 80%.

The LMG1020 driver features dead-time adjustment control capability, providing enhanced efficiency in applications such as DC-DC converters, Class D audio amplifiers, and motor drives.
