MCP14700T-E/MF

Overview

The MCP14700T-E/MF is a high-speed synchronous MOSFET driver designed to optimally drive high-side and low-side N-Channel MOSFETs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 36 ns, with rise and fall times of 10 ns. It delivers peak output currents of 2 A and 3.5 A. The component is housed in an 8-lead DFN (3x3 mm) package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Optimized for driving high-side and low-side N-Channel MOSFETs in synchronous applications
• High-speed switching performance with 36 ns propagation delay
• Supports external dead time control for enhanced bridge efficiency

Applications

• Synchronous buck converters
• Half-bridge power stages
• DC-DC converter topologies requiring fast switching

Procurement Notes

Verify the specific suffix 'MF' corresponds to the 8-DFN (3x3 mm) tape-and-reel packaging configuration as documented in the official Microchip datasheet. Ensure the order quantity aligns with standard reel sizes if bulk procurement is required. Confirm that the 'E' designation indicates the extended industrial temperature grade suitable for the intended operating environment.

Selection Notes

Select this component when a compact half-bridge driver with precise timing characteristics is required for N-Channel MOSFETs. The 3x3 mm DFN package offers space savings compared to SOIC alternatives. Consider the 36 ns propagation delay and 10 ns transition times for high-frequency switching applications where minimal dead time loss is critical.

Part Context

This part belongs to the MCP14700 family of gate drivers from Microchip Technology. It is specifically engineered for synchronous rectification applications. The 'T' suffix denotes tape-and-reel packaging, while 'MF' specifies the DFN package type. It serves as a dedicated solution for driving power switches in efficient power conversion systems.

Replacement Considerations

Direct substitutes include other MCP14700 variants such as MCP14700-E/SN or MCP14700T-EMF, provided the package footprint and electrical specifications match the design requirements. Verify pinout compatibility before substitution.
