MAX4420EPA

Overview

The MAX4420EPA is a high-speed, single-channel MOSFET gate driver manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 6 A for both sourcing and sinking. The device features non-inverting logic inputs compatible with CMOS and TTL standards. It provides symmetric rise and fall times of approximately 25 ns to 30 ns. The component is housed in an 8-pin PDIP package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Delivers high-current drive capability suitable for rapid switching of power MOSFETs
• Features low quiescent current consumption for energy-efficient operation
• Provides robust input threshold compatibility with standard digital logic families

Applications

• Switching power supplies
• DC-DC converters
• Motor controllers
• Pin-diode drivers

Procurement Notes

Verify the specific suffix 'EPA' confirms the through-hole PDIP-8 packaging variant rather than surface-mount options. Confirm RoHS compliance status as '+'. Check current availability constraints as distribution channels may report limited stock or end-of-life statuses for this legacy Maxim part number.

Selection Notes

Select this component when a single-channel, non-inverting driver with 6A peak current is required. Ensure the application utilizes N-channel or P-channel MOSFETs compatible with the specified supply voltage range. Verify that the through-hole mounting style aligns with the PCB design requirements compared to SOIC alternatives.

Part Context

This part belongs to the MAX4420 family of high-speed MOSFET drivers from Maxim Integrated. It serves as a discrete interface between low-power control logic and high-power switching elements. The device is designed to minimize dead-time losses in bridge configurations by providing fast transition times.

Replacement Considerations

Publicly confirmed substitute part numbers include TC4420, AS4420, NCP4420, and MIC4420.
