MIC4607-2YTS-T5

Overview

The MIC4607-2YTS-T5 is an obsolete 85V three-phase MOSFET gate driver manufactured by Microchip Technology. It integrates adaptive dead-time control, anti-shoot-through protection, and overcurrent protection for high-voltage applications. The device operates within a supply voltage range of 4.5V to 28V and supports programmable gate drive voltages up to 16V. It features a rise time of 20ns and a fall time of 20ns, with a maximum operating temperature of +125°C. Packaged in a 28-pin TSSOP, it delivers 1A output current per channel.

Feature Summary

• Integrates adaptive dead-time control to optimize switching efficiency and reduce cross-conduction risks in three-phase bridge configurations.
• Includes built-in anti-shoot-through and overcurrent protection mechanisms to safeguard connected MOSFETs during fault conditions.
• Supports programmable gate drive voltage levels up to 16V, allowing customization for various MOSFET gate charge requirements.

Applications

• Three-phase motor drives requiring high-voltage isolation and protection
• Industrial inverters and converters utilizing 85V bus voltages
• High-efficiency power conversion systems with adaptive timing needs

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability through authorized distributors or surplus channels is required. Ensure that any sourced units are genuine and have not been compromised due to long-term storage. Check for moisture sensitivity labels if the package has been exposed to ambient conditions. Confirm pin compatibility with existing PCB layouts before procurement.

Selection Notes

Select this part for three-phase applications requiring integrated protection features rather than discrete solutions. Consider the 28-pin TSSOP package constraints for thermal management. Verify that the input logic levels match the controlling microcontroller or FPGA outputs. Evaluate the need for programmable gate drive settings against the specific MOSFET characteristics being driven.

Part Context

The MIC4607 series belongs to Microchip's family of high-voltage three-phase MOSFET drivers. These devices are designed to simplify the design of complex power stages by integrating timing and protection functions. The -2 suffix typically denotes specific pinout or feature variations within the series compared to other variants like the MIC4607-1.

Replacement Considerations

As the MIC4607-2YTS-T5 is obsolete, direct substitutes may be limited. Review Microchip's newer three-phase driver families for functional equivalents. Ensure any replacement maintains the 85V rating and 28-pin TSSOP form factor. Verify that alternative parts support similar adaptive dead-time and overcurrent protection capabilities.
