MIC4425ZWM-TR

Overview

The MIC4425ZWM-TR is a dual low-side MOSFET driver from the MIC4423/4424/4425 family, manufactured by Microchip Technology. It features a BiCMOS/DMOS process for high reliability and robust performance in demanding electrical environments. The device provides a peak output current of 3A per channel and operates within a supply voltage range of 4.5V to 18V. It is housed in a 16-pin SOIC package with lead-free construction. Key timing parameters include rise and fall times typically around 28ns to 35ns. The driver is designed to withstand up to 5V of noise spiking on the ground pin without latch-up or logic upset.

Feature Summary

• High output current capability of 3A per channel for efficient MOSFET switching
• Robust noise immunity capable of surviving 5V ground pin spiking without latch-up
• Compatible with CMOS and TTL logic inputs for versatile interface options
• Lead-free packaging compliant with RoHS standards

Applications

• Low-side gate driving for power MOSFETs in motor control systems
• Power supply circuits requiring fast switching speeds
• Industrial automation equipment interfaces
• Battery management system drivers

Procurement Notes

Verify the specific suffix ZWM-TR indicates tape and reel packaging with a quantity of 1000 units. Confirm the operating temperature grade matches application requirements, as variants exist with different thermal ratings. Ensure the 16-SOIC footprint aligns with PCB design constraints. Check for lead-free compliance documentation if required by regulatory standards. Validate that the low-side configuration suits the target circuit topology.

Selection Notes

Select this component when a dual low-side driver with 3A peak current is required. Compare against the MIC4423 and MIC4424 families for pin compatibility and similar performance characteristics. Consider the 4.5V to 18V supply range suitability for the system voltage. Evaluate the 28ns to 35ns rise/fall times against switching frequency needs. Ensure the SOIC-16 package fits the available board space.

Part Context

The MIC4425 series represents an evolution of the earlier MIC426/427/428 family, offering improved output current and reliability. It is part of a pin-compatible lineup including MIC4423 and MIC4424, allowing for design flexibility across different current and speed requirements. The device utilizes a BiCMOS/DMOS process to enhance performance over previous generations while maintaining backward compatibility in form factor.

Replacement Considerations

The MIC4423ZWM-TR and MIC4424ZWM-TR are pin-compatible alternatives within the same family. Verify if the specific current or speed requirements of the application necessitate these variants. Ensure any substitute maintains the 16-SOIC package and low-side driver functionality.
