MXT429EJA

Overview

The MXT429EJA is a single 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 within a supply voltage range of 7V to 18V and supports CMOS and TTL logic input levels. It features fast switching characteristics with rise and fall times of 35ns, ensuring minimal propagation delay. The component is housed in an 8-CDIP package designed for through-hole mounting, suitable for industrial and commercial applications requiring robust power switching control.

Feature Summary

• Delivers high peak source and sink currents of 6A for rapid MOSFET switching
• Compatible with standard CMOS and TTL logic input thresholds
• Features low propagation delay and symmetrical rise/fall times for precise timing control

Applications

• Industrial motor control systems
• Power management circuits
• Inverter bridge drivers

Procurement Notes

Verify the specific package variant, as sources indicate both CDIP and TSSOP configurations exist under similar identifiers. Confirm RoHS compliance status and lead times directly with authorized distributors due to potential supply constraints. Ensure the selected version matches the required thermal and mechanical specifications for the target PCB layout.

Selection Notes

Select this component when a single-channel, high-current driver is needed for N-channel MOSFETs in low-side configurations. Consider the 6A output capability for driving larger power devices compared to lower-current alternatives. Evaluate the through-hole CDIP package against surface-mount requirements for the specific assembly process.

Part Context

This part belongs to the MXT429 series of gate drivers from Maxim Integrated, now part of Analog Devices. The series focuses on providing reliable control for power MOSFETs in various switching applications. The EJA suffix typically denotes the ceramic dual in-line package variant, distinguishing it from plastic or surface-mount versions within the same functional family.
