MCP14E3-E/SN

Overview

The MCP14E3-E/SN is a dual MOSFET gate driver manufactured by Microchip Technology, designed for high-speed switching applications. It features an inverting configuration with two independent drivers and outputs. The device supports a supply voltage range from 4.5 V to 18 V and delivers a peak output current of 4 A. Key electrical parameters include a rise time of 15 ns and a fall time of 18 ns. It operates within a temperature range of -40°C to +125°C and is housed in an 8-pin SOIC package.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High-speed switching capability with nanosecond-level rise and fall times
• Integrated enable pin functionality for power management and safety control

Applications

• Automotive power electronics systems requiring AEC-Q100 qualification
• Industrial motor control circuits utilizing low-side switching
• General-purpose DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'E' indicates automotive-grade reliability and 'SN' denotes the SOIC-8 surface mount package. Confirm that the component meets AEC-Q100 standards if used in automotive contexts. Ensure input logic levels are compatible with CMOS or TTL interfaces as specified in the official datasheet to guarantee proper signal integrity during operation.

Selection Notes

Select this component when dual low-side driving is required with moderate current capabilities up to 4 A. It is suitable for applications needing fast switching speeds under 20 ns. Consider the inverting logic configuration and the 4.5 V to 18 V supply range. This part is appropriate for environments demanding extended temperature operation up to 125°C.

Part Context

This device belongs to the MCP14E series of dual MOSFET drivers. It shares functional similarities with other parts in the family but is distinguished by its specific 4 A output current rating and automotive qualification. The SOIC-8 package provides a compact solution for space-constrained designs requiring dual channel isolation.

Replacement Considerations

Direct substitutes may include other dual low-side drivers from Microchip with similar current ratings and package types. Verify compatibility regarding supply voltage ranges, propagation delays, and logical inversion before substitution.
