Overview
The NCP81156MNTBG is a half-bridge gate driver IC manufactured by onsemi, designed for high-side and low-side MOSFET control. It features a non-inverting configuration within an 8-VFDFN Exposed Pad package. The device operates with a supply voltage range of 4.5 V to 13.2 V. Key timing parameters include a rise time of 16 ns and a fall time of 11 ns. It supports a wide operating temperature range from -10°C to +125°C. This component is part of the NCP81166 series and is compliant with VR12.5 standards.
Feature Summary
- Non-inverting half-bridge gate driver architecture
- VR12.5 compatible design for modern processor power stages
- Integrated high-side and low-side output drivers
Applications
- CPU core voltage regulation modules (VRMs)
- GPU power delivery systems
- Server and workstation motherboard power stages
Procurement Notes
Verify the specific suffix 'MNTBG' against the official onsemi datasheet to confirm the exact tape-and-reel packaging and environmental compliance status. Ensure the ordering information matches the required lead times and factory specifications provided by authorized distributors. Cross-reference the RoHS declaration with current regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when a non-inverting half-bridge driver is required for VR12.5 compliant designs. Compare the 16 ns rise and 11 ns fall times against system switching frequency requirements. Evaluate the 4.5 V to 13.2 V supply range compatibility with existing logic levels. Consider the 8-VFDFN package size for PCB layout constraints compared to alternative packages in the same series.
Part Context
This part belongs to the NCP81166 series of gate drivers from onsemi. It shares functional similarities with other members like the NCP81151 but differs in supply voltage ranges and specific feature sets. The series targets high-performance computing applications requiring precise gate drive control for synchronous buck converters.
Replacement Considerations
Check for direct pin-compatible substitutes within the NCP81166 family. Verify if variants with different suffixes offer identical electrical characteristics or modified packaging options. Confirm that any replacement maintains the non-inverting configuration and VR12.5 compatibility.
