MAX4420CPA

Overview

The MAX4420CPA is a high-speed, single-channel MOSFET gate driver manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 4.5V to 18V and delivers a peak output current of 6A for both sourcing and sinking. The device features non-inverting logic inputs compatible with CMOS and TTL standards. Typical rise and fall times are specified at 30ns. It is housed in an 8-pin PDIP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides high-current drive capability for efficient switching of N-channel and P-channel MOSFETs.
• Features low quiescent current consumption suitable for battery-powered applications.
• Includes robust input threshold levels ensuring reliable operation with standard digital logic families.

Applications

• Industrial motor control systems
• Automotive power management circuits
• Aerospace electronic equipment

Procurement Notes

Verify the specific suffix 'CPA' indicates the PDIP package variant when ordering. Confirm RoHS compliance status as '+T' or '+' suffixes typically denote lead-free versions. Check current availability as distribution may be limited. Ensure the supplier provides official datasheets matching the exact part number to avoid pinout mismatches between SOIC and PDIP packages.

Selection Notes

Select this component when a single-channel, non-inverting driver with 6A peak current is required. It is suitable for applications needing fast switching speeds with minimal propagation delay. Consider the PDIP package for through-hole prototyping or specific board layouts requiring larger pitch spacing compared to surface-mount alternatives.

Part Context

This part belongs to the MAX4420 series of high-speed MOSFET drivers. It is designed to interface directly with microcontrollers or logic gates to drive power switches. The series offers various package options including SOIC and DIP to accommodate different manufacturing requirements.

Replacement Considerations
