GaN half-bridge driver with integrated protection
The LMG3422R030RQZT: It integrates fault protection including current limiting, over-temperature shutdown, and undervoltage lockout (UVLO), reducing external component count in power-stage designs.
Package and layout considerations
Housed in a 54-VQFN Exposed Pad package measuring 12x12 mm, the LMG3422R030RQZT requires careful thermal pad soldering to the PCB ground plane for effective heat dissipation. The surface-mount footprint and exposed pad demand a solder stencil design that matches the datasheet's recommended land pattern to avoid voiding under the thermal pad.
