MCP14A0453-E/MS

Overview

The MCP14A0453-E/MS is a dual MOSFET gate driver from Microchip Technology, packaged in an 8-MSOP. It operates on a single supply voltage ranging from 4.5V to 18V and delivers a peak output current of 4.5A. Both Channel A and Channel B feature inverted outputs. The device is characterized by low breakdown current, fast rise and fall times of 12ns, and short propagation delay. It functions as a high-speed, low-side driver with matched performance across channels.

Feature Summary

• Dual channel configuration with both outputs inverted
• High peak drive current capability of 4.5A
• Fast switching characteristics with 12ns rise and fall times
• Low breakdown current for enhanced protection

Applications

• Low-side MOSFET driving in power conversion circuits
• Industrial motor control systems
• High-speed switching applications requiring matched dual outputs

Procurement Notes

Verify the specific suffix MSVAO or MS against the required datasheet revision. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the operating temperature range meets system requirements. Check availability through authorized distributors as stock levels vary. Validate pinout compatibility during PCB layout finalization.

Selection Notes

Select this component when dual inverted low-side driving is required. The 4.5A current rating suits medium-power MOSFETs. Consider the 8-MSOP package for space-constrained designs. Verify that the 4.5V to 18V supply range aligns with the system logic levels. Match the 12ns timing specifications with the target switching frequency requirements.

Part Context

This part belongs to the MCP14A series of high-speed MOSFET drivers. It complements other variants like the MCP14A0302 which offers non-inverting outputs. The series focuses on providing robust gate drive solutions for industrial and consumer applications. The MSOP-8 package is common across several models in this family for consistent form factor.

Replacement Considerations

The MCP14A0453T-E/MSVAO is a tape-and-reel variant of the same functional device. Direct substitutes within the same family include parts with similar current ratings but different output configurations. Verify pin-to-pin compatibility before swapping with non-Microchip alternatives.
