MAX4426EPA+

Overview

The MAX4426EPA+ is a dual-channel, low-side power MOSFET gate driver manufactured by Analog Devices Inc. (Maxim Integrated). It converts TTL/CMOS logic inputs into high-current outputs capable of driving power MOSFETs. The device operates from a single supply voltage ranging from 4.5V to 18V and features an inverting logic configuration. Packaged in an 8-pin PDIP for through-hole mounting, it supports data rates up to 15MHz with propagation delays as low as 30ns. The component includes internal shoot-through protection to prevent simultaneous conduction in half-bridge applications.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High peak output current capability for rapid switching of power devices
• Integrated shoot-through protection mechanism to ensure safe operation
• TTL and CMOS compatible input logic levels

Applications

• Low-side gate driving in DC-DC converters
• Motor control circuits requiring precise MOSFET switching
• Inverter bridge configurations
• Power supply management systems

Procurement Notes

Verify the specific suffix 'EPA+' indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the package type matches the required 8-PDIP footprint for your PCB layout. Check for any obsolescence notices or lifecycle changes directly from Analog Devices, as this component may have been superseded by newer iterations within the MAX4426 family.

Selection Notes

Select this component when a dual low-side driver with integrated protection is required for cost-sensitive designs. Ensure the supply voltage range aligns with your system's power rails. Consider the PDIP package constraints if surface-mount space is limited. Verify that the 15MHz speed rating meets the switching frequency requirements of your target application without excessive thermal dissipation.

Part Context

The MAX4426 belongs to the Maxim Integrated line of high-speed MOSFET drivers, designed to simplify the interface between logic controllers and power stages. As part of the MAX4426 series, it shares functional similarities with other variants but offers specific pinout and performance characteristics tailored for general-purpose power switching. The EPA+ designation confirms environmental compliance standards set by the manufacturer.

Replacement Considerations

Direct replacements include the MAX4426EPA and MAX4426ESA+. Verify pin compatibility and electrical specifications before substitution. Newer alternatives in the MAX4427 or MAX4428 families offer non-inverting options or quad-channel configurations.
