MIC4426CM-TR

Overview

The MIC4426CM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent inverting outputs capable of sourcing and sinking 1.5 A peak current. The device operates on a single supply voltage ranging from 4.5 V to 18 V. It accepts standard CMOS or TTL logic inputs and provides fast switching with typical rise and fall times of 20 ns and 29 ns, respectively. The component is housed in an 8-SOIC surface-mount package and is designed for efficient power management applications requiring robust gate drive performance.

Feature Summary

• Dual independent low-side drivers with inverting configuration
• High peak output current capability of 1.5 A for rapid MOSFET switching
• Compatible with standard CMOS and TTL logic input levels
• Operates within a wide single-supply voltage range

Applications

• DC-DC converter synchronous rectification
• Motor control bridge driving
• Power supply gate drive circuits

Procurement Notes

Verify the specific suffix CM-TR against official Microchip documentation to confirm the 8-SOIC package and tape-and-reel packaging format. Ensure compatibility with the target PCB footprint and reflow soldering profile. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a dual low-side driver with moderate 1.5 A output current is required. It is suitable for applications where inverting logic signals are acceptable. Consider the 8-SOIC package constraints and thermal dissipation requirements. Compare against higher current variants if load demands exceed 1.5 A or non-inverting configurations are necessary.

Part Context

This part belongs to the MIC4426 family of high-speed MOSFET drivers. It shares functional similarities with other members like the MIC4427 (non-inverting) but differs in logical configuration. The series is designed for general-purpose power switching applications, offering a balance between speed and drive strength in a compact surface-mount form factor.
