NCP81166MNTBG

Overview

The NCP81166MNTBG is a dual-channel MOSFET gate driver manufactured by onsemi, designed for high-side and low-side switching applications. It operates within a supply voltage range of 4.5 V to 13.2 V and supports surface-mount installation in a reel package. The device features two independent drivers with rise and fall times of 16 ns and 11 ns respectively, ensuring rapid switching performance. It functions reliably across an extended temperature range from -10°C to +125°C and is compatible with VR12.5 standards.

Feature Summary

• Dual-channel configuration providing independent high-side and low-side gate drive capabilities
• VR12.5 compatibility for integration into standard power management architectures
• Fast switching characteristics with specified nanosecond-level rise and fall times

Applications

• High-side and low-side MOSFET driving in power conversion circuits
• Compliance with VR12.5 specification requirements for processor power delivery
• General purpose gate driving for silicon-based power switches

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements as indicated in the manufacturer's product data sheet. Cross-reference the datasheet revision history to validate electrical parameters and pinout configurations prior to implementation.

Selection Notes

Select this component when dual-channel isolation is required for synchronous rectification or half-bridge topologies. Consider the 13.2 V maximum supply limit and the -10°C to +125°C operating range for environmental constraints. Evaluate the 16 ns rise and 11 ns fall times against system switching frequency requirements to ensure adequate performance without excessive losses.

Part Context

This part belongs to the NCP81166 series of gate drivers from onsemi, categorized under PMIC power management ICs. It is distinct from other onsemi products like the NCP81611 buck controller or NCP51200 DDR regulators. The MNTBG suffix indicates a specific surface-mount packaging variant suitable for automated assembly processes.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Generic gate drivers may not match the VR12.5 compatibility or specific timing characteristics. Verify pin-to-pin compatibility and electrical parameter alignment before substituting.
