MIC4425CWM

Overview

The MIC4425CWM is a dual low-side MOSFET gate driver manufactured by Microchip Technology, housed in a 16-pin SOIC package. It provides a nominal output peak current of 3 A per channel. The device operates within a supply voltage range up to 18 V and supports an operating temperature range extending to 70 °C. It features buffer or inverter-based logic interfaces compatible with CMOS and TTL standards.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High peak output current capability of 3 A for rapid switching
• Robust noise immunity allowing survival of ground pin spikes up to 5 V
• Latch-up free operation under specified power and voltage ratings

Applications

• Low-side MOSFET switching in motor control circuits
• Power supply gate drive applications requiring high current
• Industrial automation systems utilizing BiCMOS/DMOS drivers

Procurement Notes

Verify the specific suffix 'C' against official Microchip documentation to confirm temperature grade and lead-free status. Confirm package integrity as Rochester Electronics distributes this part. Ensure compatibility with existing PCB footprints for SOIC-16 components before procurement.

Selection Notes

Select this component for applications requiring dual low-side driving with 3 A peak current. It is suitable for environments needing latch-up protection and noise tolerance. Compare against the MIC4425ZWM series for extended temperature ranges if operating conditions exceed 70 °C.

Part Context

This part belongs to the MIC4425 family of highly reliable BiCMOS/DMOS buffer/driver MOSFET drivers. It serves as a higher output current version of the MIC4426/4427/4428 series. The family is designed for demanding electrical environments and offers improved performance over predecessor models like the MIC426/427/428.

Replacement Considerations

MIC4425ZWM is a pin-compatible alternative within the same family offering different manufacturing specifications.
