MIC4428CM-TR

Overview

The MIC4428CM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-SOIC surface-mount package. It provides independent inverting and non-inverting outputs with peak source and sink currents of 1.5A each. The device operates on a supply voltage range of 4.5V to 18V and supports logic levels compatible with both CMOS and TTL standards. Typical rise and fall times are specified at 20ns and 29ns respectively, ensuring fast switching performance. The component is rated for an operating junction temperature range from -40°C to 150°C.

Feature Summary

• Dual-channel configuration providing independent inverting and non-inverting outputs for flexible control applications
• High peak output current capability of 1.5A for efficient driving of power MOSFETs
• Wide supply voltage operation supporting 4.5V to 18V ranges for various system architectures

Applications

• Low-side switching control for N-channel and P-channel MOSFETs
• Industrial motor drive systems requiring robust gate driving
• Power supply circuits utilizing high-frequency switching topologies

Procurement Notes

Verify the specific suffix 'CM' against the official Microchip datasheet to confirm commercial temperature grade (-40°C to 85°C) versus industrial or automotive variants. Ensure the 'TR' designation matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before procurement.

Selection Notes

Select this component when a dual-channel low-side driver with moderate 1.5A peak current is required. It is suitable for applications needing both inverting and non-inverting signals from a single IC. Consider the 8-SOIC package constraints and thermal dissipation capabilities relative to the PCB layout. Verify that the input logic voltage thresholds align with the controlling microcontroller or FPGA output levels.

Part Context

This part belongs to the MIC442x series of MOSFET gate drivers, which are designed for high-speed switching applications. The series typically includes variants with different current ratings and channel counts. The MIC4428 specifically focuses on dual-channel low-side driving, offering a balance between performance and pin count for compact designs.

Replacement Considerations

Compatible substitutes include the TC4428 family (e.g., TC4428COA, TC4428EOA) which shares similar electrical characteristics and pinout configurations. Other dual low-side drivers from Microchip such as the MIC4427 may serve as alternatives depending on specific current or speed requirements.
