Overview
The MIC4423ZWM is a dual low-side MOSFET driver from the MIC4423/4424/4425 family, manufactured by Microchip Technology. It utilizes a BiCMOS/DMOS process to deliver high reliability in demanding electrical environments. The device features two independent channels with a nominal output peak current of 3 A. It is housed in a 16-pin SOIC package (PDSO16) and operates within a maximum junction temperature of 70 °C. The component is lead-free and RoHS compliant, designed for buffer or inverter-based MOSFET driving applications.
Feature Summary
- High-output current capability suitable for demanding electrical environments
- Immunity to latch-up under all conditions within power and voltage ratings
- Robust ground pin tolerance capable of surviving up to 5V noise spiking
- BiCMOS/DMOS construction for enhanced reliability compared to predecessor families
Applications
- Data storage systems
- Medical equipment
- Datacom modules
Procurement Notes
Verify the specific ordering suffix to confirm the package type and tape-and-reel configuration, as variations exist within the product line. Ensure the procurement documentation explicitly states compliance with RoHS standards and lead-free manufacturing processes. Cross-reference the manufacturer part number against official Microchip databases to validate authenticity and avoid counterfeit components.
Selection Notes
Select this component when a dual-channel low-side driver with 3A peak current is required. It serves as a higher output current version of the MIC4426/4427/4428 series while maintaining pin compatibility. Consider this device for designs needing improved noise immunity and latch-up protection over previous generations like the MIC426/427/428.
Part Context
The MIC4423ZWM belongs to the MIC4423/4424/4425 family of dual MOSFET drivers. These devices are positioned as robust, high-current solutions derived from earlier Micrel and Microchip technologies. The ZWM suffix typically denotes a specific tube packaging format for the 16-lead SOIC variant, distinguishing it from tape-and-reel options.
Replacement Considerations
The MIC4424 and MIC4425 are pin-compatible members of the same family. Verify if the non-inverting (MIC4424) or specific variant requirements match the design needs before substituting.
