MIC4224YMME-TR

Overview

The MIC4224YMME-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 4 A per channel. The device features non-inverting logic configuration and utilizes an 8-pin MSOP package with exposed pad for thermal management. Key timing characteristics include rise and fall times of 15 ns, ensuring fast switching performance suitable for high-frequency applications.

Feature Summary

• Dual-channel low-side gate driver architecture
• High peak output current capability of 4 A
• Non-inverting input logic configuration
• Fast switching speeds with 15 ns rise and fall times

Applications

• DC-DC converter circuits
• Motor control systems
• Power supply designs requiring low-side switching

Procurement Notes

Verify the exact suffix (e.g., -TR) matches the required reel quantity and tape-and-reel packaging specifications. Confirm the operating temperature range aligns with system requirements, as industrial variants may differ from commercial grades. Ensure the MSOP-8EP package footprint matches the PCB layout design before finalizing procurement orders.

Selection Notes

Select this component when a dual low-side driver with moderate current drive is required. Compare against higher current alternatives if load capacitance exceeds standard limits. Verify that the 4.5 V minimum supply voltage meets the system's lowest operational rail. Consider thermal dissipation needs given the 4 A peak current in the compact MSOP package.

Part Context

This part belongs to Microchip's MIC42xx series of MOSFET gate drivers. It is designed for efficient switching of N-channel power MOSFETs in low-side configurations. The series emphasizes reliability and speed for general-purpose power electronics applications.

Replacement Considerations

Check for direct pin-compatible substitutes such as other dual low-side drivers from Microchip or competitors. Verify equivalent current drive capabilities and propagation delays to ensure circuit stability during replacement.
