MAX4428CSA+T

Overview

The MAX4428CSA+T is a dual high-speed MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It features independent inverting and non-inverting outputs with peak output currents of 1.5A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 18V and supports logic input levels of 0.8V (VIL) and 2.4V (VIH). Typical rise and fall times are 20ns. It is housed in an 8-SOIC package and is designed for driving N-channel and P-channel MOSFETs.

Feature Summary

• Dual channel configuration providing independent inverting and non-inverting drive signals
• High peak output current capability of 1.5A for efficient MOSFET switching
• Compatible with standard logic families through defined input threshold voltages

Applications

• Driving N-channel and P-channel power MOSFETs
• Low-side gate drive circuits
• Isolated gate driver interfaces

Procurement Notes

Verify the specific suffix 'CSA' corresponds to the 8-SOIC plastic package variant when ordering. Confirm that the '+T' designation indicates tape-and-reel packaging if required for automated assembly. Ensure the supplier provides RoHS compliance documentation, as standard commercial variants typically adhere to these environmental standards. Cross-reference the manufacturer part number with official Analog Devices catalogs to confirm current production status and availability constraints.

Selection Notes

Select this component when dual, complementary gate drive signals are required from a single input source. It is suitable for applications needing moderate speed switching with 1.5A drive strength. Consider the 4.5V minimum supply voltage constraint against system power rails. The SOIC package offers a balance between thermal performance and board space compared to larger DIP packages.

Part Context

This device belongs to the MAX4428 family of gate drivers, which includes variations such as the MAX4428MJA/883B for military specifications and other package options like CERDIP. The CSA+T variant specifically targets general-purpose industrial and commercial applications requiring reliable MOSFET control without the stringent qualification requirements of aerospace-grade parts.

Replacement Considerations

Direct substitutes include other dual low-side MOSFET drivers with similar 1.5A output current and 4.5V-18V supply ranges. Check pinout compatibility for SOIC-8 packages before substitution. Variants like the MAX4428EUA or MAX4428ESA may offer different temperature grades or packaging but maintain functional equivalence.
