Power Driver Modules Procurement Notes

Verify the specific suffix RQS corresponds to the 52-pin VQFN package configuration. Confirm that the ordering part number matches the exact ZVD-enabled variant required for your design. Ensure compatibility with the recommended operating conditions regarding supply voltage and thermal management requirements specified in the datasheet.

Power Driver Modules Selection Notes

Select this component when zero-voltage switching support is required within a 650V GaN topology. Consider the adjustable slew rate capability for EMI mitigation. Evaluate the thermal resistance metrics for heat dissipation needs. Compare against LMG3527R030 if zero-current detection is preferred instead of zero-voltage detection.

Power Driver Modules Part Context

This device belongs to the LMG352xR030 family of integrated GaN FETs. It shares the same core power stage and protection architecture as the LMG3522R030 and LMG3527R030. The primary distinction lies in the detection features: LMG3526R030 provides ZVD, while LMG3527R030 offers ZCD. All variants utilize the same 52-pin VQFN package.

Power Driver Modules FAQ

What is the function of the ZVD pin?

The ZVD pin outputs a pulse signal indicating that zero-voltage switching has been achieved in the current switching cycle.

How is the slew rate controlled?

The slew rate is adjusted by connecting a resistor from the RDRV pin to the SOURCE pin, allowing control between 20V/ns and 150V/ns.

What fault conditions trigger the FAULT pin?

The FAULT pin asserts low during overcurrent, short-circuit, overtemperature, VDD UVLO, or high-impedance RDRV pin conditions.
