MIC4424ZWM

Overview

The MIC4424ZWM 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 3 A for both sourcing and sinking. The device features non-inverting logic inputs compatible with TTL levels, specifically 0.8 V for low input and 2.4 V for high input. Typical switching performance includes a rise time of 28 ns and a fall time of 32 ns. It is housed in a 16-pin SOIC package and supports an operating junction temperature range from 0°C to 150°C.

Feature Summary

• Dual independent low-side drivers providing isolated control for two N-channel or P-channel MOSFETs
• High peak output current capability of 3 A ensures rapid charging and discharging of gate capacitance
• Non-inverting configuration simplifies interface design with standard digital logic sources
• Extended thermal stability allows reliable operation in high-temperature industrial environments

Applications

• Motor control systems requiring precise timing for power stage switching
• Power supply topologies utilizing synchronous rectification
• Industrial automation equipment driving multiple MOSFET loads
• Battery management systems managing high-current discharge paths

Procurement Notes

Verify the specific suffix ZWM indicates the 16-SOIC surface-mount package variant distinct from through-hole options. Confirm RoHS compliance status as REACH compliant and MSL level 2 for moisture sensitivity handling during assembly. Ensure the ordering quantity matches the tube or tape-and-reel format required by your production line equipment. Cross-reference the manufacturer part number against official Microchip databases to avoid counterfeit components.

Selection Notes

Select this component when dual independent low-side drive is required without internal bootstrap circuitry. The 3 A peak current rating suits medium-power applications where fast switching transitions are critical. Consider the 16-SOIC footprint for PCB space constraints compared to larger DIP packages. Verify that the input logic voltage thresholds align with the controlling microcontroller or FPGA outputs before integration into the design.

Part Context

This part belongs to the MIC4424 family of dual low-side gate drivers designed for robust performance in demanding power electronics applications. It serves as a bridge between low-power logic controllers and high-power MOSFET switches. The series emphasizes speed and reliability, making it suitable for various industrial and consumer power conversion tasks requiring efficient energy management.

Replacement Considerations

Direct substitutes include other dual low-side drivers from the same family such as the MIC4424ZN for through-hole applications. Check pinout compatibility and electrical specifications like peak current and supply voltage ranges before swapping. Alternative manufacturers may offer similar functionality but require verification of thermal characteristics and input threshold levels.
