MCP14A0454-E/SN

Overview

The MCP14A0454-E/SN is a dual low-side MOSFET gate driver from Microchip Technology, housed in an 8-SOIC surface-mount package. It provides non-inverting outputs with a peak drive current of 4.5 A per channel. The device operates within a supply voltage range of 4.5 V to 18 V and supports CMOS logic inputs. Key timing parameters include a rise time of 12 ns, fall time of 14 ns, and maximum propagation delay of 31 ns. It functions reliably across an industrial temperature range of -40°C to +125°C and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Dual-channel architecture with matched high-speed performance for synchronized switching applications
• Non-inverting output configuration simplifies control logic integration
• Automotive-grade reliability certified under AEC-Q100 standards
• Low quiescent current consumption for efficient power management

Applications

• Automotive powertrain and body electronics systems
• Industrial motor control drives
• High-frequency DC-DC converter topologies
• Inverter bridge circuits requiring matched switching characteristics

Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-SOIC package variant when sourcing. Confirm AEC-Q100 qualification requirements align with target automotive or industrial specifications. Ensure input logic levels are compatible with standard CMOS interfaces. Check for updated datasheet revisions regarding thermal dissipation guidelines for the SOIC-8 footprint.

Selection Notes

Select this component for applications requiring matched rise and fall times to minimize cross-conduction losses in half-bridge configurations. The 4.5 A drive capability suits medium-power MOSFETs. Consider the 8-SOIC package constraints for PCB layout and thermal management compared to larger packages like TDFN-8 if higher power dissipation is anticipated.

Part Context

This part belongs to the MCP14A0454 family of dual low-side gate drivers. Variants such as MCP14A0454-E/MS offer the same electrical performance in an MSOP-8 package, while MCP14A0454-E/MNY utilizes a TDFN-8 form factor. All variants share the core 4.5 A drive strength and non-inverting functionality designed for robust MOSFET switching.

Replacement Considerations

Direct substitutes include MCP14A0454-E/MS (MSOP-8) and MCP14A0454-E/MNY (TDFN-8). Verify pinout compatibility and thermal resistance differences when changing package types. Ensure replacement parts maintain the same AEC-Q100 grade if automotive compliance is required.
