MCP14E4-E/SN

Overview

The MCP14E4-E/SN is a dual high-speed power MOSFET gate driver manufactured by Microchip Technology. It features two non-inverting outputs capable of sourcing and sinking 4 A of peak current. The device operates within a supply voltage range of 4.5 V to 18 V and supports CMOS and TTL logic inputs. It exhibits fast switching characteristics with rise and fall times of 30 ns. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High-current output stage designed for rapid switching of power devices
• Automotive qualification ensuring reliability in demanding operational environments

Applications

• Automotive power management systems requiring robust gate driving
• Industrial motor control circuits utilizing low-side switching
• DC-DC converter topologies needing isolated or non-isolated drive signals

Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 tube packaging configuration when ordering. Confirm that the AEC-Q100 qualification status meets your project's automotive reliability requirements. Ensure input logic levels are compatible with standard CMOS or TTL interfaces before integration into the final design.

Selection Notes

Select this component when dual low-side driving capability is required with moderate current demands. The 4 A output current is suitable for most medium-power MOSFETs. Consider the non-inverting configuration if signal phase preservation is necessary. The wide operating temperature range makes it appropriate for harsh environmental conditions compared to commercial-grade alternatives.

Part Context

This part belongs to the MCP14E3/4/5 family of dual high-speed power MOSFET drivers. These devices share similar architectural features but differ in output current capabilities and specific package options. The MCP14E4 variant specifically targets applications requiring balanced performance between speed and drive strength for dual-channel configurations.

Replacement Considerations

Direct substitutes include other members of the MCP14E series such as MCP14E3 or MCP14E5, provided their current ratings align with load requirements. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
