Overview
The NCP5351DR2G is a dual MOSFET gate driver from onsemi, designed for synchronous buck converters. It features a half-bridge configuration with high-side and low-side outputs in an SOIC-8 package. The device operates within a supply voltage range of 4.5 V to 18 V and supports output currents up to 3 A. It includes integrated bootstrap diodes and dead-time control to prevent shoot-through. The component is qualified to AEC-Q100 standards for automotive applications and operates across a temperature range of -40°C to +125°C.
Feature Summary
- Optimized design for synchronous buck converter applications
- Integrated bootstrap diode and dead-time control
- Automotive qualification to AEC-Q100 standards
Applications
- Synchronous buck converters
- Automotive power management systems
- DC-DC conversion modules
Procurement Notes
Verify the specific suffix 'DR2G' against the manufacturer's current datasheet to confirm packaging and tape-and-reel specifications. Ensure the component meets AEC-Q100 requirements if used in automotive contexts. Cross-reference the part number with official onsemi channels to avoid counterfeit components and confirm end-of-life status before finalizing procurement plans.
Selection Notes
Select this component when a robust, automotive-grade gate driver is required for synchronous buck topologies. The integrated bootstrap diode simplifies circuit design by reducing external component count. Consider the 3 A peak drive current capability for driving medium-power MOSFETs efficiently while maintaining low propagation delay and reliable operation under varying load conditions.
Part Context
The NCP5351 belongs to onsemi's portfolio of power management ICs tailored for high-efficiency switching applications. As a dedicated half-bridge driver, it complements other PMIC solutions by providing precise control over power stage switching. Its automotive qualification aligns with industry demands for reliability in vehicle electronics and industrial power systems.
Replacement Considerations
Check for direct pin-compatible alternatives within the NCP53xx series or comparable automotive-qualified drivers from other manufacturers. Verify that substitute parts match the 3 A drive current and operating voltage range. Ensure any replacement maintains AEC-Q100 certification if the application requires automotive compliance.
