MCP14700-E/MF

Overview

The MCP14700-E/MF is a dual-input synchronous MOSFET driver designed for high-speed switching applications. It features a half-bridge configuration with two outputs, supporting N-channel MOSFETs. The device operates within a supply voltage range of 4.5 V to 5.5 V and delivers peak output currents of 2 A source and 3.5 A sink. Key electrical parameters include a propagation delay of 36 ns, rise/fall times of 10 ns, and a quiescent current of 80 μA. It is housed in an 8-lead DFN (3x3 mm) package and is qualified under AEC-Q100 standards for automotive reliability.

Feature Summary

• Supports external dead time control for optimized switching performance
• Compatible with CMOS and TTL logic inputs
• Designed for driving low Figure-of-Merit (FOM) N-channel MOSFETs

Applications

• Automotive power management systems
• Synchronous rectification circuits
• High-side and low-side N-channel MOSFET gate driving

Procurement Notes

Verify the specific suffix -MF indicates the DFN-8 package variant distinct from other pinouts. Confirm AEC-Q100 qualification status if automotive compliance is required. Check moisture sensitivity levels prior to soldering. Ensure supply voltage remains strictly between 4.5 V and 5.5 V to prevent damage. Validate lead-free RoHS compliance through official manufacturer documentation.

Selection Notes

Select this component when a compact, automotive-grade solution is needed for driving N-channel MOSFETs in half-bridge topologies. The DFN-8 package offers space savings compared to SOIC variants. Consider the 36 ns delay and 10 ns transition times for high-frequency applications. Ensure the load type matches N-channel devices only. Verify thermal requirements against the 125°C maximum junction temperature rating.

Part Context

This part belongs to the MCP14700 family of synchronous MOSFET drivers manufactured by Microchip Technology. It serves as a specialized interface between logic controllers and power switches. The -E/MF designation specifies the automotive-grade version in a DFN-8 package. It complements other drivers in the series that may offer different packages or non-automotive grades.

Replacement Considerations

Check for direct substitutes within the MCP14700 family, such as the MCP14700-E/SN, which shares similar electrical characteristics but uses an SOIC-8 package. Verify pinout compatibility before substitution. Ensure any alternative meets the same AEC-Q100 and voltage specifications.
