Gate Driver Applications

• Plasma display panel applications
• Motor drive converter circuits
• Switching power supplies
• High-power DC-DC converters

Gate Driver Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure that the selected variant matches the required package type and thermal characteristics for the intended application environment. Cross-reference ordering information with authorized distributors to confirm current availability status and lead time requirements prior to finalizing procurement plans.

Gate Driver Selection Notes

Select this component for applications requiring robust high-side switching with significant noise immunity. The integrated noise elimination circuit makes it suitable for high dv/dt environments. Consider the 4 A drive capability for medium-power MOSFETs and IGBTs. Verify that the system design accommodates the bootstrap voltage requirements and that the input logic levels align with the controller outputs.

Gate Driver Part Context

The FAN73711M belongs to the FAN7371 series of high-side gate drivers from onsemi.
