NCP4429DR2

Overview

The NCP4429DR2 is a high-speed MOSFET driver from onsemi, packaged in an SOIC-8 surface-mount case. It features two drivers with a fixed supply voltage of 13.2V. The device operates within a temperature range of 0°C to 85°C and has physical dimensions of 5mm length by 1.5mm height. Electrical performance includes a rise time of 16ns and a fall time of 11ns.

Feature Summary

• High-speed switching capability for efficient power management
• Integrated dual-driver architecture for simplified circuit design
• Surface-mount construction for automated assembly

Applications

• General-purpose MOSFET gate driving
• Power supply control circuits
• Industrial motor drive interfaces

Procurement Notes

Verify the specific suffix DR2G against the datasheet to confirm package type and tape-and-reel specifications. Ensure the operating environment stays within the 0°C to 85°C limit. Cross-reference the manufacturer part number with official onsemi documentation to avoid counterfeit components.

Selection Notes

Select this component when a dedicated dual-channel driver is required for synchronous rectification or half-bridge applications. The fixed 13.2V supply simplifies biasing compared to adjustable regulators. Consider the 16ns rise time for switching frequency requirements.

Part Context

This part belongs to the NCP4429 series of high-speed MOSFET drivers. It serves as a buffer or inverter for power switches. The SOIC-8 package provides a compact footprint suitable for dense PCB layouts. It complements other onsemi power management solutions.

Replacement Considerations

Check for direct pin-compatible alternatives such as the NCP4429P if leaded packaging is preferred. Verify electrical parameters like rise/fall times match system requirements before substitution.
