MAX4420CSA-T

Overview

The MAX4420CSA-T is a low-side MOSFET gate driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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, supporting single-channel configuration. It provides symmetric rise and fall times of approximately 25 ns to 30 ns. The component is housed in an 8-SOIC surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Provides high-current switching capability with 6 A peak drive strength for efficient MOSFET control
• Features non-inverting input logic that ensures direct signal transmission without phase inversion
• Supports fast switching speeds with typical propagation delays around 25 ns to minimize power loss

Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring N-channel MOSFET actuation
• Power management systems utilizing single-supply operation

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'C' designation aligns with the required commercial temperature grade (-40°C to +85°C). Ensure the SOIC-8 footprint matches the target PCB layout dimensions. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or material declarations prior to final procurement decisions.

Selection Notes

Select this component when a single-ended, non-inverting low-side driver is required for N-channel MOSFETs. It is suitable for applications needing moderate speed and high current drive from a single supply voltage between 4.5 V and 18 V. Consider the 8-SOIC package constraints for thermal dissipation and board space. Verify that the input logic levels are compatible with the controlling microcontroller or FPGA outputs.
