MIC4607-1YTS-TR

Overview

The MIC4607-1YTS-TR is an 85V three-phase half-bridge MOSFET gate driver manufactured by Microchip Technology. It integrates six drivers in a VQFN-28 package, supporting supply voltages from 5.25V to 16V with a maximum output current of 1A per channel. The device features non-inverting logic, 20ns rise/fall times, and propagation delays up to 75ns. It operates within a temperature range of -40°C to +125°C and includes adaptive dead-time control, shoot-through protection, and overcurrent protection capabilities.

Feature Summary

• Integrates adaptive dead-time control to optimize switching efficiency and minimize cross-conduction risks in three-phase applications.
• Includes built-in shoot-through protection and overcurrent protection mechanisms to safeguard connected MOSFETs during fault conditions.
• Supports dual inputs for flexible control configurations while maintaining non-inverting logic operation.

Applications

• Three-phase motor drives
• Brushless DC (BLDC) motor control systems
• Industrial power conversion circuits

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the '1' designation aligns with the required dual-input configuration. Ensure the VQFN-28 package footprint matches the target PCB layout. Cross-reference the datasheet revision date to confirm compatibility with latest thermal and electrical specifications before finalizing procurement.

Selection Notes

Select this component for designs requiring integrated protection features such as adaptive dead-time and shoot-through prevention. It is suitable for high-voltage three-phase applications up to 85V. Consider the 1A peak drive current and 20ns transition speeds for medium-frequency switching requirements. Verify that the 5.25V to 16V supply range meets the system's logic and bootstrap voltage needs.

Part Context

The MIC4607 series belongs to Microchip's family of three-phase MOSFET gate drivers designed for robust industrial and automotive applications. This specific variant, MIC4607-1YTS-TR, utilizes a TSSOP or VQFN package depending on the exact sub-model suffix interpretation, though official data links it to the 28-pin form factor. It serves as a specialized solution for driving six MOSFETs in a half-bridge configuration without external timing components.

Replacement Considerations

Direct substitutes include other MIC4607 variants such as MIC4607-1YML-TR if package differences are acceptable. Verify pinout compatibility between TSSOP and VQFN packages if swapping physical footprints. Check if alternative drivers offer similar adaptive dead-time features if exact model availability is limited.
