MIC4424CWM

Overview

The MIC4424CWM 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 per channel. The device features rise and fall times of 35 ns, with a maximum propagation delay of 75 ns. It functions at temperatures between 0°C and +70°C and accepts CMOS or TTL logic inputs. Housed in a 16-pin SOIC package, it consumes 2.5 mA of operating current.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High peak output current capability of 3 A for rapid switching
• Compatible with standard CMOS and TTL logic input levels

Applications

• Low-side MOSFET switching in power conversion circuits
• Motor drive interface stages
• General-purpose high-speed digital isolation buffers

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's latest documentation to confirm temperature grade and RoHS status. Confirm availability as distribution channels may list this component as obsolete or end-of-life. Ensure the SOIC-16 package matches the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual low-side driving is required with moderate speed and high current capacity. It is suitable for applications where CMOS or TTL compatibility is necessary. Consider thermal dissipation limits if operating near maximum voltage or current specifications. Verify that the 3 A peak current meets the gate charge requirements of the intended MOSFETs.

Part Context

This part belongs to the MIC4424 family of dual MOSFET drivers from Microchip. It shares pinout compatibility with other variants in the series but differs in electrical characteristics such as current drive and speed. The C suffix typically denotes a commercial temperature range variant within the product line.
