MIC4420YM-TR

Overview

The MIC4420YM-TR is a single-channel, 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 6 A. The device features non-inverting logic with typical rise and fall times of 25 ns. It is housed in an 8-pin SOIC package (3.90 mm width) and is supplied in tape and reel packaging.

Feature Summary

• Provides high-speed switching capability for driving large capacitive loads with minimal propagation delay.
• Delivers robust 6 A peak source and sink current to ensure reliable MOSFET turn-on and turn-off.
• Features a low on-resistance output stage to minimize power dissipation during operation.

Applications

• Driving N-channel power MOSFETs in DC-DC converter circuits
• Gate drive stages in motor control applications
• High-frequency power switching systems requiring fast transition times

Procurement Notes

Verify the specific suffix 'YM' corresponds to the required 8-pin SOIC package variant. Confirm that the 'TR' designation indicates tape and reel packaging compatible with automated assembly equipment. Ensure the operating temperature range meets system requirements, as standard variants typically cover -40°C to +85°C. Cross-reference the manufacturer part number with official Microchip documentation to validate RoHS compliance status.

Selection Notes

Select this component when a single-channel, low-side driver with 6 A peak current is required. It is suitable for applications needing non-inverting logic and fast switching speeds around 25 ns. Consider alternative packages like MSOP if space constraints exist, or higher current drivers if load requirements exceed 6 A. Verify input logic voltage levels align with the controller's output specifications.

Part Context

The MIC4420 series consists of high-speed, high-current MOSFET drivers designed for efficient power management. The YM-TR variant specifically denotes the surface-mount SOIC-8 package configuration with tape and reel delivery. This family is widely used in industrial and consumer electronics for controlling power switches in inverters and converters.

Replacement Considerations

MIC4420YMM-TR: Alternative version utilizing an 8-MSOP package instead of SOIC-8, offering similar electrical performance with a smaller footprint.
