MXT429CPA

Overview

The MXT429CPA is a single-channel, low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It provides a peak output current of 6A to drive N-channel power MOSFETs efficiently. The device operates with a minimum supply voltage of 7V and supports CMOS and TTL logic input levels. Key electrical characteristics include rise and fall times of 35ns each, with a quiescent supply current of 5mA. It functions within an operating temperature range of 0°C to +70°C and is housed in a surface-mount package.

Feature Summary

• Delivers 6A peak source/sink current for rapid MOSFET switching
• Compatible with standard CMOS and TTL logic input signals
• Optimized for low-side configuration applications

Applications

• N-channel MOSFET gate driving in power conversion circuits
• Low-side switching control in motor drive systems
• General-purpose power management IC interfaces

Procurement Notes

Verify the exact manufacturer part number against official Analog Devices documentation, as the prefix 'MXT' may indicate a specific variant or legacy designation distinct from standard Maxim Integrated naming conventions. Confirm RoHS compliance status and packaging type directly with the supplier, as availability data suggests restricted supply conditions for this specific identifier.

Selection Notes

Select this component when a high-current, single-channel driver is required for low-side N-channel MOSFET control. Ensure the application logic levels match the supported CMOS/TTL inputs and that the supply voltage remains above the 7V minimum threshold. Consider thermal dissipation requirements given the 471mW power dissipation rating during operation.

Part Context

This component belongs to the power management integrated circuit category, specifically within the gate drivers subcategory. It is designed to interface between low-power logic controllers and high-power switching elements, facilitating efficient energy transfer in electronic systems requiring robust MOSFET actuation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative gate drivers from the same manufacturer family.
