MCP1403-E/MF

Overview

The MCP1403-E/MF is a dual high-speed power MOSFET driver manufactured by Microchip Technology. It features two independent low-side drivers with inverting logic, designed for efficient switching of external N-channel MOSFETs. The device operates within a supply voltage range of 4.5V to 18V and delivers a peak output current of 4.5A. It utilizes an 8-lead DFN-S package (6x5 mm) suitable for surface-mount applications. The component supports an operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

Feature Summary

• Dual independent low-side gate driver channels with inverting logic configuration
• High peak output current capability of 4.5A for rapid MOSFET switching
• Compact 8-lead DFN-S surface-mount package design
• Extended industrial temperature rating for robust operation

Applications

• Power management systems requiring efficient MOSFET control
• DC-DC converter topologies utilizing external N-channel switches
• Motor drive circuits needing high-speed gate driving
• Industrial automation equipment with strict thermal requirements

Procurement Notes

Verify the specific suffix 'MF' corresponds to the 8-lead DFN-S package when ordering. Confirm that the inverting logic aligns with your control signal requirements. Ensure the supply voltage remains within the 4.5V to 18V operational limits during system integration. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when dual isolated gate driving is necessary for N-channel MOSFETs. The 4.5A peak current supports fast switching speeds, reducing conduction losses. The DFN-S package offers a smaller footprint compared to SOIC alternatives. Consider the inverting logic nature; non-inverting variants may be required if signal phase alignment differs.

Part Context

This part belongs to the MCP1403 family of dual MOSFET drivers. Other variants include MCP1403-E/SN and MCP1403-E/SO, which differ primarily in packaging. The 'E' designation typically indicates an extended temperature range. The 'MF' suffix specifically identifies the DFN-S package type used in this model.

Replacement Considerations

Direct substitutes include MCP1403-E/SN and MCP1403-E/SO, though these utilize different packages (SOIC). Verify pin compatibility and thermal performance when swapping between package types. Ensure the replacement maintains the 4.5A output current specification.
