MIC4480YME-T5

Overview

The MIC4480YME-T5 is a dual low-side gate driver IC manufactured by Microchip Technology. It features two independent channels designed to drive N-channel MOSFETs. The device operates with a maximum supply voltage of 32 V and provides peak output currents of 2.5 A for both sourcing and sinking. Electrical characteristics include a source resistance of 6 ohms and a sink resistance of 3 ohms. Propagation delays are specified at 160 ns for high-to-low transitions and 70 ns for low-to-high transitions. The component is housed in an 8-SOIC package with an exposed pad, measuring 0.154 inches (3.90 mm) in width.

Feature Summary

• Dual independent channel configuration for simultaneous control of separate loads
• Low-side driving architecture optimized for N-channel MOSFET applications
• High peak current capability supporting rapid switching of power devices

Applications

• Driving N-channel MOSFETs in DC-DC converter circuits

Procurement Notes

Verify the specific suffix T5 indicates tape and reel packaging when ordering. Confirm the part status as obsolete through official Microchip channels prior to procurement planning. Ensure compatibility with existing PCB footprints for the 8-SOIC exposed pad package. Validate that the 32 V maximum supply rating aligns with system design requirements.

Selection Notes

Select this component for designs requiring dual independent low-side drivers with moderate current capabilities. The 2.5 A peak output current suits standard power MOSFET gates. Consider the propagation delay specifications for timing-sensitive applications. The exposed pad package offers thermal advantages for surface-mount assembly processes.

Part Context
