Product details

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.

Frequently asked questions

What fault protection does LMG3422R030RQZT include?

It includes fixed current limiting, over-temperature protection, and undervoltage lockout (UVLO) on the supply rail.
