MAX4427ESA-T

Overview

The MAX4427ESA-T is a dual low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 18V and supports both N-channel and P-channel MOSFETs. The device features non-inverting inputs with peak output currents of 1.5A for both sourcing and sinking. Typical rise and fall times are 20ns, facilitating fast switching speeds. It is housed in an 8-SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual channel configuration for independent control of two low-side switches
• Supports both N-channel and P-channel MOSFET gate driving requirements
• Non-inverting logic input compatibility for straightforward signal interfacing

Applications

• Switching power supplies
• DC-DC converter circuits
• Motor control systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the component status as active or obsolete through official manufacturer channels prior to procurement planning. Ensure the 8-SOIC footprint matches the target PCB layout design specifications accurately.

Selection Notes

Select this component for applications requiring dual low-side drive capability with moderate current output. Consider the 1.5A peak current rating against the total gate charge of the target MOSFETs. Verify that the 4.5V minimum supply voltage aligns with the system's available logic levels.
