MIC4423BWM

Overview

The MIC4423BWM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent drivers with a peak output current of 3 A and operates within a supply voltage range of 4.5 V to 18 V. The device utilizes a SOIC-16 surface-mount package and supports CMOS and TTL logic inputs. It provides fast switching performance with rise and fall times of 35 ns, ensuring efficient control of external power MOSFETs in demanding electrical environments.

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
• Robust design prevents latch-up under specified power and voltage conditions

Applications

• Motor drive systems requiring precise low-side switching
• Power conversion circuits utilizing external MOSFETs
• Industrial equipment with high-speed switching requirements

Procurement Notes

Verify the specific suffix 'BWM' against official Microchip documentation to confirm package type and temperature rating. Confirm RoHS compliance status as indicated in datasheets, noting that some variants may differ. Check for end-of-life or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when dual low-side driving with 3 A peak current is required. Ensure the application voltage stays within the 4.5 V to 18 V range. Verify that the SOIC-16 package fits the PCB layout constraints and that the operating temperature range meets system thermal requirements.

Part Context

This part belongs to the MIC4423/4424/4425 family of dual 3A-Peak Low-Side MOSFET Drivers. These devices are based on a BiCMOS/DMOS process and serve as higher output current versions of earlier families like the MIC4426/4427/4428. All members of this family share pin compatibility.

Replacement Considerations

MIC4424BWM and MIC4425BWM are pin-compatible alternatives within the same family. Verify if non-inverting (MIC4424) or other specific configurations are needed instead of the inverting MIC4423.
