MCP1404T-E/SO

Overview

The MCP1404T-E/SO is a dual high-speed power MOSFET gate driver manufactured by Microchip Technology. It provides independent low-side drive for two N-channel MOSFETs or IGBTs with a peak output current of 4.5A. The device operates within a supply voltage range of 4.5V to 18V and features non-inverting logic inputs. Key electrical characteristics include rise and fall times of approximately 12ns, ensuring fast switching performance. It is housed in an 8-pin SOIC package and is designed for industrial applications requiring robust gate drive capabilities.

Feature Summary

• Dual independent low-side gate drivers for simultaneous control of two power switches
• High peak output current capability of 4.5A for rapid MOSFET charging and discharging
• Non-inverting input configuration simplifies interface with standard logic controllers
• Fast propagation delay and transition times support high-frequency switching operations

Applications

• Industrial motor drives and inverters
• DC-DC converter topologies requiring isolated or non-isolated low-side driving
• Power supply systems utilizing N-channel MOSFETs or IGBTs

Procurement Notes

Verify the specific suffix 'E/SO' confirms the 8-pin SOIC package and industrial temperature rating. Ensure compatibility with your PCB footprint, as the SOIC-8 outline must match your design constraints. Confirm that the 4.5A peak current aligns with your target MOSFET's gate charge requirements for optimal switching efficiency.

Selection Notes

Select this component when dual low-side driving is required without the complexity of high-side bootstrap circuits. It is suitable for applications where cost-effective, high-current drive is needed for N-channel devices. Consider thermal management if operating near maximum current limits, and ensure the input logic levels are compatible with the 4.5V minimum supply voltage.

Part Context

This part belongs to Microchip's MCP14xx series of MOSFET drivers, known for reliability in industrial environments. The MCP1404 variant specifically addresses dual low-side needs, distinguishing it from single-driver or high-side/low-side combinations like the MCP14LH series. It serves as a direct replacement for legacy dual low-side drivers in existing designs.

Replacement Considerations

Direct substitutes may include other dual low-side drivers with similar 4.5A current ratings and SOIC-8 packaging, such as variants from the MCP1407 family if pinouts differ, or comparable parts from other manufacturers offering identical electrical specifications and package dimensions.
