NCP81168MNTBG

Overview

The NCP81168MNTBG is a high-side and low-side MOSFET gate driver designed for VR12.5 compatible applications. It features two drivers with non-inverting logic, operating on a supply voltage range of 4.5 V to 5.5 V. The device supports N-channel MOSFETs with rise and fall times of approximately 15 ns and 10 ns respectively. It operates within a temperature range of -10°C to +125°C and is available in an 8-DFN (2x2) package.

Feature Summary

• VR12.5 compatible design for modern processor power delivery
• Integrated interleaved conduction protection mechanism
• Configurable dead-time control for optimized switching performance
• Enable shutdown functionality for system power management

Applications

• Processor voltage regulation modules (VRMs)
• Server and workstation power supplies
• High-density point-of-load conversion systems

Procurement Notes

Verify the specific suffix MNTBG against the manufacturer's current datasheet to confirm package dimensions and marking codes. Ensure compatibility with VR12.5 specifications if used in new designs. Check for end-of-life notices or alternative recommendations from onsemi as this component may have reached obsolescence status in some regions.

Selection Notes

Select this component when VR12.5 compliance is required for processor power stages. The integrated interleaved conduction protection reduces output capacitor stress. Verify that the 4.5V to 5.5V supply range matches the controller's output. The small 8-DFN package suits space-constrained PCB layouts.

Part Context

Part of the NCP8116x series from onsemi, focusing on multi-phase gate driving solutions. This model specifically targets non-inverting logic applications requiring precise timing control. It complements other PMIC components in complete power management subsystems for computing platforms.

Replacement Considerations

Check onsemi documentation for direct pin-compatible substitutes within the NCP8116x family. Verify electrical parameters such as drive current and propagation delay before substituting with generic alternatives.
