MIC4424BM

Overview

The MIC4424BM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features a 16-pin SOIC package and supports a supply voltage range of 4.5 V to 18 V. The device provides a peak output current of 3 A with rise and fall times of 35 ns each. It operates within a temperature range of 0 °C to +70 °C, has a maximum propagation delay of 75 ns, and draws a typical operating supply current of 2.5 mA.

Feature Summary

• Dual-channel architecture for independent low-side switching control
• High peak output current capability for rapid capacitive load drive
• Non-inverting logic input configuration compatible with TTL standards

Applications

• Power management systems requiring efficient MOSFET switching
• Industrial motor control applications
• DC-DC converter topologies

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm availability status as product lifecycles may change. Cross-reference pinouts with similar family members if substituting.

Selection Notes

Select this component when dual low-side driving is required with moderate speed and high current capacity. Consider the 16-pin SOIC form factor for surface mount assembly. Evaluate thermal dissipation needs relative to the 960 mW power rating in enclosed environments.

Part Context

This part belongs to the MIC4424 series of high-speed MOSFET drivers. It shares functional similarities with other variants like the MIC4424ZN and MIC4424YM but differs in packaging and operational temperature specifications. The series is designed for reliable service in demanding electrical environments.

Replacement Considerations

MIC4424BWM is a direct pin-compatible alternative with identical electrical characteristics but utilizes an SOIC-16 package variant.
