MAX626MJA/883B

Overview

The MAX626MJA/883B is a dual low-side power MOSFET gate driver manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for MIL-STD-883B compliance. It features a CERDIP-8 through-hole package and operates within a supply voltage range of 4.5 V to 18 V. The device provides independent drivers with rise and fall times of 30 ns each. It supports CMOS and TTL logic inputs and draws a maximum operating supply current of 8 mA. The unit functions reliably across an extended temperature range from -55°C to +125°C.

Feature Summary

• Dual independent low-side gate driver configuration for simultaneous control of two N-channel or P-channel power MOSFETs
• Compliant with MIL-STD-883B standards ensuring suitability for rigorous military and aerospace applications
• Capable of driving high-speed power switches with symmetric 30 ns rise and fall times
• Compatible with standard CMOS and TTL logic input levels for straightforward interface integration

Applications

• Military-grade power conversion systems requiring radiation-hardened or high-reliability components
• Aerospace motor control circuits demanding precise switching timing and robust isolation
• High-reliability industrial inverters and solid-state power controllers
• Avionics power distribution units utilizing low-side switching architectures

Procurement Notes

Verify that the specific part number suffix matches the required MIL-STD-883B qualification level, as commercial equivalents lack this certification. Confirm the package type is the specified CERDIP-8 variant suitable for through-hole mounting. Ensure the supplier provides traceability documentation consistent with defense industry standards. Check for any obsolescence notices or limited availability status before finalizing procurement plans.

Selection Notes

Select this component when dual isolated low-side drive signals are necessary for synchronous rectification or half-bridge configurations in harsh environments. Consider the 4.5 V minimum supply voltage constraint against your system's rail stability. Evaluate the 30 ns propagation delay against your maximum switching frequency requirements. Verify that the 8 mA output current capability sufficiently charges the gate capacitance of your target MOSFETs without excessive distortion.
