MAX4426MJA/883B

Overview

The MAX4426MJA/883B is a dual high-speed MOSFET driver manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for military and aerospace applications. It features two independent low-side drivers capable of sourcing and sinking 1.5A peak output current. The device operates within a supply voltage range of 4.5V to 18V and supports both inverting and non-inverting logic inputs compatible with CMOS and TTL standards. Packaged in an 8-CERDIP (CDIP) format, it ensures reliable performance across an extended temperature range from -55°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side power MOSFETs or IGBTs.
• High-current drive capability delivering 1.5A peak source and sink currents for rapid switching.
• Military-grade qualification compliant with MIL-STD-883 standards for harsh environment reliability.
• Flexible input compatibility supporting standard CMOS and TTL logic thresholds.

Applications

• Gate driving for power MOSFETs and IGBTs in military-grade power conversion systems
• Switching regulators requiring high-speed, isolated gate control in aerospace environments
• Industrial motor control circuits utilizing ruggedized low-side driver configurations

Procurement Notes

Verify that the specific ordering suffix matches the required package style and thermal characteristics. Confirm that the component meets all necessary environmental certifications for the intended deployment. Ensure that the supplier provides traceable documentation validating the MIL-STD-883 compliance status. Check for any obsolescence notices or lifecycle restrictions before finalizing procurement plans.

Selection Notes

Select this component when high-speed switching of low-side power devices is required in extreme temperature conditions. The dual-channel design simplifies circuit layout for half-bridge or synchronous rectifier topologies. Consider the 1.5A drive strength as sufficient for medium-power MOSFETs without external buffering. Evaluate the CERDIP package constraints against available board space and mounting requirements.
