MCP14A0454T-E/SN

Overview

The MCP14A0454T-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 output current of 4.5 A per channel. The device operates within a supply voltage range of 4.5 V to 18 V and features matched rise and fall times of 12 ns. It supports a maximum propagation delay of 31 ns and draws a typical quiescent current of 620 µA. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Dual-channel architecture with independent high-current push-pull outputs
• Non-inverting logic configuration for direct signal control
• Matched propagation delays and transition times for synchronized switching
• Low quiescent current consumption for energy-efficient standby modes

Applications

• Synchronous buck converter low-side drive
• Half-bridge power stage implementation
• General-purpose MOSFET switching applications

Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-SOIC package variant when sourcing. Confirm that the 'E' designation indicates automotive-grade qualification if required by your design specifications. Ensure compatibility with the 4.5 V to 18 V supply range for your target application environment.

Selection Notes

Select this component when dual low-side driving with matched timing characteristics is required. The 4.5 A output capability suits medium-power MOSFETs. Consider the SOIC-8 footprint constraints and thermal dissipation requirements under continuous load conditions relative to alternative packages like MSOP or TDFN.

Part Context

This part belongs to the MCP14A0454 family of high-speed gate drivers. It shares functional similarities with other variants such as MCP14A0454T-E/MS and MCP14A0454T-E/MNY, differing primarily in packaging style. The series is designed for robust performance in industrial and automotive power management systems.

Replacement Considerations

Direct pin-compatible alternatives include MCP14A0454T-E/MS (MSOP-8) and MCP14A0454T-E/MNY (TDFN-8). Verify package dimensions and thermal properties before substitution.
