MIC44F19YML-TR

Overview

The MIC44F19YML-TR is a high-speed, dual MOSFET driver manufactured by Microchip Technology. It features two independent output channels designed to drive N-channel power MOSFETs with low on-resistance and fast switching times. The device operates from a supply voltage range of 3V to 20V and provides peak output currents of up to 2A source and 4A sink per channel. It includes built-in shoot-through protection to prevent simultaneous conduction in half-bridge configurations.

Feature Summary

• Dual independent output channels for driving N-channel MOSFETs
• Integrated shoot-through protection mechanism
• High peak output current capability for rapid switching
• Wide operating supply voltage range

Applications

• Half-bridge and full-bridge motor control circuits
• DC-DC converter gate drive stages
• Inverter applications requiring isolated or non-isolated drive signals
• Power management systems utilizing high-side and low-side switching

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the 'YML' package designation matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system's thermal design constraints. Cross-reference the datasheet revision date to ensure compatibility with latest electrical specifications.

Selection Notes

Select this component when dual independent MOSFET drive is required with integrated protection. Consider the 2A/4A peak current ratings against load capacitance requirements. Evaluate the 3V to 20V supply range against available system voltages. Verify logic input compatibility with microcontroller or FPGA output levels.

Part Context

This part belongs to Microchip's MIC44xx series of MOSFET drivers. It is designed for applications requiring reliable switching of power MOSFETs with minimal external components. The series offers various configurations including single, dual, and quad drivers with different current capabilities and protection features.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family such as other MIC44xx variants. Verify equivalent peak current ratings and supply voltage ranges. Ensure any substitute maintains similar propagation delay characteristics and shoot-through protection functionality.
