MIC4424YM-TR

Overview

The MIC4424YM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology in an 8-SOIC package. It provides non-inverting outputs with peak source and sink currents of 3A each. The device operates on a supply voltage range of 4.5V to 18V. Logic input thresholds are defined at 0.8V for VIL and 2.4V for VIH. Typical rise and fall times are 28ns and 32ns, respectively. The junction temperature range extends from -40°C to 150°C.

Feature Summary

• Dual independent low-side drivers for N-channel and P-channel MOSFETs
• High peak output current capability of 3A per channel
• Fast switching performance with typical rise and fall times under 35ns
• Compatible with TTL logic levels for direct interface

Applications

• Power management systems requiring efficient MOSFET switching
• DC-DC converter topologies utilizing low-side drive configurations
• Industrial motor control applications driving power switches
• Automotive electronics systems requiring robust gate drive signals

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the 'YM' designation corresponds to the SOIC-8 package variant. Ensure compatibility with the required operating temperature range of -40°C to 150°C for the intended application environment. Cross-reference the datasheet for any recent manufacturing changes or pinout updates.

Selection Notes

Select this component for applications requiring dual low-side drive with high current capacity. The 3A peak current supports fast charging and discharging of gate capacitances. The wide supply voltage range accommodates various logic and power rail configurations. Consider thermal dissipation requirements given the 960mW power dissipation rating in the SOIC-8 package.

Part Context

This part belongs to the MIC442x family of BiCMOS DMOS buffer/driver/MOSFET drivers. It serves as a higher output current version compared to the MIC4426/4427/4428 series. The device is designed for driving other loads requiring low impedance and high peak currents. It is suitable for general-purpose switching applications beyond just MOSFETs.

Replacement Considerations

Check for MIC4424YM (tube packaging) if reel quantity is not required. Verify MIC4423 or MIC4425 variants if single or different channel counts are needed. Ensure substitute parts maintain the same 3A peak current and 8-SOIC footprint.
