MIC4123YML-TR

Overview

The MIC4123YML-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features an inverting configuration with peak output currents of 3A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 20V and supports logic input levels of 0.8V (VIL) and 2.4V (VIH). Typical rise and fall times are 11ns. It is housed in an 8-MLF® (2x2mm) package and functions across a temperature range of -40°C to +125°C TJ.

Feature Summary

• Provides high-speed switching capability with 3A peak drive current for efficient MOSFET control.
• Features an inverting logic configuration to simplify interface with standard control signals.
• Designed for robust operation over a wide industrial temperature range up to 125°C.

Applications

• DC-DC converter circuits requiring low-side switching
• Motor control systems utilizing N-channel MOSFETs
• Power management modules needing fast transient response

Procurement Notes

Verify the specific suffix 'YML-TR' confirms the 8-MLF package and tape-and-reel packaging format. Ensure compatibility with the target PCB footprint dimensions of 2x2mm. Confirm RoHS compliance status if required by assembly specifications. Check moisture sensitivity level (MSL 3) handling requirements during storage and soldering processes.

Selection Notes

Select this component when a dual inverting low-side driver with 3A current capability is required. It is suitable for applications demanding fast switching speeds around 11ns. Consider the 8-MLF package size for space-constrained designs. Verify that the input logic thresholds align with the system's microcontroller or FPGA output levels.

Part Context

This part belongs to the MIC412x series of improved high-speed MOSFET drivers from Microchip Technology, formerly Micrel. The series includes variants like MIC4124, MIC4125, and MIC4126, which differ in non-inverting configurations or current ratings. The MIC4123 specifically denotes the dual inverting low-side variant.

Replacement Considerations

Direct substitutes include MIC4124YML-TR (non-inverting), MIC4125YML-TR (dual non-inverting/low side), and MIC4126YML-TR (1.5A dual low side). Verify pinout compatibility and electrical parameters before substitution.
