NCP5358MNTXG

Overview

The NCP5358MNTXG is a dual high-side and low-side gate driver IC manufactured by onsemi, designed for desktop power systems. It operates within an input voltage range of 4.5 V to 18 V and supports supply voltages up to 20 V. The device features independent high-side and low-side outputs with configurable dead-time control to prevent shoot-through currents. It includes integrated bootstrap diodes and protection mechanisms such as under-voltage lockout (UVLO) and thermal shutdown. Packaged in a compact QFN-20 format, it ensures reliable switching performance for synchronous buck converters.

Feature Summary

• Dual-channel gate driver architecture supporting synchronous buck topologies
• Integrated bootstrap diodes eliminating external component requirements
• Configurable dead-time control for optimized switching efficiency
• Comprehensive protection including under-voltage lockout and thermal shutdown

Applications

• Desktop computer motherboard VRMs
• Server and workstation power distribution modules
• High-current DC-DC converter stages
• Industrial power supply systems

Procurement Notes

Verify the complete part number NCP5358MNTXG against official onsemi documentation to ensure correct suffix identification. Confirm RoHS compliance status through current material declarations. Check for any recent product change notices or lifecycle updates that may affect availability or specifications before finalizing procurement plans.

Selection Notes

Select this component when designing synchronous buck converters requiring isolated drive signals for both high-side and low-side MOSFETs. Ensure the application voltage does not exceed the 20 V absolute maximum rating. Consider the QFN-20 package thermal characteristics for PCB layout optimization. Verify compatibility with the controller's logic levels and required switching frequencies for the target power stage design.

Part Context

This device belongs to onsemi’s portfolio of gate drivers tailored for desktop and notebook power applications. It complements controllers like the NCP5359 series by providing the necessary drive strength and isolation. The NCP5358 focuses on delivering robust performance for multi-phase power delivery systems commonly found in modern computing hardware.

Replacement Considerations

Direct replacements should be sought from the NCP535x family, such as the NCP5359A, if pin compatibility and feature sets align. Verify that alternative devices support the same input voltage range and package dimensions. Cross-reference datasheets to ensure equivalent dead-time configuration options and protection features are present.
