MIC4423BM-TR

Overview

The MIC4423BM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology. It features an inverting logic configuration and is housed in an 8-SOIC surface-mount package. The device operates within a supply voltage range of 4.5V to 18V. It supports IGBT and N-channel MOSFET loads with a single channel configuration. The component is rated for a junction temperature range of -40°C to 150°C.

Feature Summary

Provides high-output current capability suitable for demanding electrical environments
Designed to prevent latch-up under all conditions within specified power and voltage ratings
Capable of surviving significant noise spiking on the ground pin without damage or logic upset

Applications

Driving N-channel MOSFETs in power conversion circuits
IGBT gate drive applications requiring reliable switching
Industrial motor control systems

Procurement Notes

Verify the specific suffix 'BM' against the manufacturer's official documentation to confirm package dimensions and thermal characteristics. Ensure the 'TR' designation matches the required reel packaging format for automated assembly processes. Cross-reference the RoHS status and environmental compliance data directly from the latest datasheet, as regulatory classifications may vary by production batch.

Selection Notes

Select this component when a low-side driving configuration with high peak output current is required. The inverting logic input simplifies interface design with standard digital controllers. Consider the wide operating temperature range for applications exposed to extreme thermal conditions. Verify that the 8-SOIC footprint aligns with the existing PCB layout constraints.

Part Context

This part belongs to the MIC4423/4424/4425 family of dual 3A-peak low-side MOSFET drivers. These devices utilize a BiCMOS/DMOS process for enhanced reliability compared to earlier generations. The family members are pin-compatible, allowing for flexible design upgrades while maintaining board compatibility.
