MCP14A0454-E/MNY

Overview

The MCP14A0454-E/MNY is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two non-inverting outputs capable of sourcing and sinking 4.5 A each. The device operates within a supply voltage range of 4.5 V to 18 V and supports CMOS logic inputs. Key electrical parameters include a maximum propagation delay of 31 ns, rise and fall times of 14 ns, and a quiescent current of 620 uA. It is housed in an 8-pin TDFN package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Dual-channel architecture with matched high-speed performance for synchronized switching
• Non-inverting output configuration simplifies control logic integration
• Automotive-grade reliability certified under AEC-Q100 standards
• Low quiescent current consumption enhances energy efficiency in standby modes

Applications

• Automotive power management systems
• Motor control circuits requiring precise low-side switching
• Industrial inverters and converters
• Battery management system (BMS) topologies

Procurement Notes

Verify the specific suffix MNY corresponds to the TDFN-8 package and tube packaging format when ordering. Confirm that the AEC-Q100 qualification meets your automotive grade requirements. Ensure input voltage levels are compatible with standard CMOS logic families to prevent interface issues during operation.

Selection Notes

Select this component when dual isolated low-side driving is required with matched timing characteristics. The 4.5 A peak current capability suits medium-power MOSFETs. Consider the TDFN-8 footprint constraints and thermal dissipation limits of 1.85 W during PCB layout planning compared to larger packages.

Part Context

This part belongs to the MCP14A0454 series of high-speed gate drivers. It shares functional similarities with other variants like the MCP14A0454T-E/MSVAO but differs in package type and manufacturing lot specifications. The series focuses on providing robust switching performance for power electronics applications.

Replacement Considerations

Direct substitutes may include other dual 4.5A non-inverting gate drivers from Microchip or competitors offering identical pinouts and electrical specs. Verify package compatibility and thermal performance before swapping.
