MIC4479YM-T5

Overview

The MIC4479YM-T5 is a high-speed MOSFET gate driver manufactured by Microchip Technology, designed for efficient switching control in power electronics applications. It operates within a supply voltage range of 4.5 V to 18 V and supports peak output currents of up to 2 A for both sourcing and sinking. The device features adjustable rise and fall times to optimize electromagnetic interference (EMI) performance while maintaining fast switching speeds. Packaged in an 8-lead SOIC surface-mount package, it includes built-in dead-time control and shoot-through protection to prevent simultaneous conduction in half-bridge configurations.

Feature Summary

• Provides robust drive capability with 2 A peak source/sink current for rapid MOSFET switching
• Features adjustable rise and fall times to balance switching speed and EMI reduction
• Includes integrated dead-time control and shoot-through protection for reliable half-bridge operation

Applications

• High-frequency DC-DC converters
• Motor control systems
• Inverter circuits

Procurement Notes

Verify the exact suffix 'T5' against official Microchip documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through the manufacturer's latest product change notifications. Ensure the component matches the specific pinout and electrical characteristics defined in the current datasheet revision before integration into production designs.

Selection Notes

Select this component when designing circuits requiring precise control over switching transitions to minimize electromagnetic interference. The adjustable timing features allow designers to tailor performance for specific efficiency or noise requirements. Consider the thermal dissipation capabilities of the SOIC-8 package relative to the expected duty cycle and ambient operating conditions during system layout.
