Procurement Notes

Verify the complete part number including the suffix 'ADR2G' to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the selected variant matches the required operating temperature range and package dimensions for your specific PCB layout constraints.

Selection Notes

Select this component when a dedicated half-bridge driver with 3 A drive capability is required for medium-frequency switching applications. It is suitable for designs utilizing MOSFETs or IGBTs requiring fast switching speeds. Consider the 8-pin SOIC package size and the 8 V to 19 V supply range compatibility with your system's logic and power levels.

Part Context

This device belongs to the NCP513xx series of gate drivers from onsemi, which are engineered for high-efficiency power conversion. The series typically includes variants with different voltage ratings and drive strengths, catering to diverse industrial and automotive power management needs. The NCP51313 specifically targets applications needing balanced high-side and low-side drive performance.

Replacement Considerations
