MIC4604YMT-TR

Overview

The MIC4604YMT-TR is an 85V half-bridge MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 5.25V to 16V and delivers peak output currents of 1.5A source and 1A sink. The device features fast switching characteristics, including a typical propagation delay of 39ns and rise/fall times of 20ns for a 1nF capacitive load. It supports logic input thresholds of 0.8V (VIL) and 2.2V (VIH). Packaged in a 10-TDFN (2.5x2.5mm) surface-mount format, it functions as a non-inverting driver suitable for high-frequency applications.

Feature Summary

• High-speed switching with 39ns propagation delay and 20ns rise/fall times

• Low logic input thresholds enabling direct interface with various logic families
• Compact 10-TDFN package design optimized for space-constrained PCB layouts

Applications

• Motor drive systems requiring precise half-bridge control
• Industrial power conversion circuits
• High-frequency DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the 10-TDFN footprint matches your PCB land pattern. Ensure the 5.25V minimum supply voltage aligns with your system's logic levels. Check RoHS compliance status for environmental regulations. Validate the 1.5A/1A current ratings against your MOSFET gate charge requirements.

Selection Notes

Select this component for applications demanding fast switching speeds and compact form factors. The 85V rating suits medium-voltage half-bridge configurations. Consider the 10-TDFN package for thermal performance and board space efficiency. Verify compatibility with your microcontroller logic levels given the 0.8V/2.2V thresholds. Evaluate the 1.5A peak current capability against the target MOSFET's gate capacitance needs.

Part Context

The MIC4604 series represents Microchip's portfolio of half-bridge drivers derived from Micrel semiconductor technology. This family targets motor control and power supply applications requiring reliable high-side and low-side MOSFET driving. The YMT variant specifically utilizes a thermally enhanced TDFN package. The TR suffix denotes reel packaging for automated assembly processes.

Replacement Considerations

Cross-reference with other MIC4604 variants such as MIC4604YM or MIC4604YM-TR if different packaging is required. Verify pinout compatibility before substituting with similar half-bridge drivers from other manufacturers. Ensure voltage ratings and current capabilities meet or exceed original specifications.
