MAX4420CPA+

Overview

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

Feature Summary

• Provides high-current drive capability for efficient switching of N-channel and P-channel MOSFETs.
• Features a supply-independent three-state PWM input logic configuration.
• Supports direct interface with standard CMOS and TTL logic families.

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity damage during assembly processes.

Selection Notes

Select this component when a robust low-side driver with 6A peak current is required for driving power MOSFETs. The non-inverting configuration simplifies control logic integration. Consider the 8-pin PDIP package for through-hole mounting applications where surface mount options are unsuitable. Verify that the input logic voltage levels match the system's microcontroller or controller outputs.
