MCP14628-E/SN

Overview

The MCP14628-E/SN is a dual MOSFET gate driver designed to optimally drive both high-side and low-side N-channel MOSFETs in non-isolated configurations. It operates within a supply voltage range of 4.5 V to 5.5 V, delivering source and sink currents of 2 A. The device features fast switching characteristics with rise and fall times of 20 ns and a propagation delay of 35 ns. Packaged in an 8-pin SOIC, it supports surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual channel architecture for simultaneous high-side and low-side N-channel MOSFET control
• High current output capability of 2 A source and sink per channel
• Fast switching performance with 20 ns rise/fall times and 35 ns propagation delay
• AEC-Q100 qualified for automotive reliability standards

Applications

• Synchronous buck power converter circuits
• Compact isolated power supplies
• Non-isolated motor drive interfaces

Procurement Notes

Verify the specific suffix 'SN' confirms the 8-pin SOIC package variant. Confirm the '-E' grade designation aligns with the required industrial temperature range of -40°C to +85°C. Ensure the ordering quantity matches the manufacturer's tube packaging requirements rather than reel quantities used for other variants like the T-series.

Selection Notes

Select this component when a compact, non-isolated dual driver is required for synchronous rectification or half-bridge applications. The fixed 4.5 V to 5.5 V supply range limits use cases to standard 5 V logic systems. The 2 A output current is sufficient for moderate-power MOSFETs but may require external buffering for larger devices.

Part Context

This part belongs to Microchip's MCP1462x family of dual MOSFET drivers. It shares functional similarities with the MCP14627 and MCP14628T series but differs in package type and shipping format. The SN suffix specifically denotes the small outline integrated circuit package, distinguishing it from DFN or tape-and-reel alternatives.

Replacement Considerations

• MCP14628-E/MF (DFN-8 package)
• MCP14628T-E/MF (DFN-8 tape and reel)
