MIC4607-2YTS-TR

Overview

The MIC4607-2YTS-TR is a three-phase half-bridge MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 5.25 V to 16 V and supports up to 85 V bus voltages. The device integrates six drivers with an output current capability of 1 A per channel. Key electrical parameters include rise and fall times of 20 ns, maximum propagation delay of 75 ns, and maximum on/off delays of 35 ns. It functions in non-inverting logic configuration with TTL-compatible inputs. The component operates between -40°C and +125°C and draws 600 µA in quiescent state. It is housed in a 28-pin VQFN package.

Feature Summary

• Integrates adaptive dead-time control to optimize switching efficiency and reduce cross-conduction risks.
• Includes dedicated shoot-through protection mechanisms to safeguard connected MOSFETs during commutation.
• Features high-speed signal transmission with symmetric rise and fall times for precise timing control.
• Supports robust operation in high-voltage environments up to 85 V with integrated overcurrent protection capabilities.

Applications

• Three-phase motor drive systems
• High-efficiency power supply inverters
• Industrial AC/DC conversion circuits

Procurement Notes

Verify the specific suffix 'YTS' confirms the TSSOP-28 package variant rather than the standard YML QFN package. Ensure the datasheet revision matches the required thermal and electrical specifications. Confirm RoHS compliance status through official Microchip documentation prior to integration. Validate that the 85V rating aligns with the target application's bus voltage requirements.

Selection Notes

Select this component when a three-phase topology is required with integrated protection features. The TSSOP-28 package offers a suitable footprint for applications where board space allows for larger surface-mount components compared to QFN variants. Consider the 1 A peak drive current sufficient for medium-power MOSFETs. Evaluate the 75 ns propagation delay against system switching frequency requirements to ensure adequate timing margins.

Part Context

This part belongs to the MIC4607 family of three-phase gate drivers designed for high-reliability power electronics. It complements other variants like the MIC4607A which may offer enhanced performance metrics or different packaging options. The series targets industrial and automotive applications requiring robust phase control and integrated safety features without external discrete protection components.

Replacement Considerations

The MIC4607A-1YML-TR serves as a functional alternative within the same family, offering similar three-phase driving capabilities. Verify pinout compatibility and package differences (TSSOP vs. VQFN) before substitution. Check if the specific 'A' variant provides improved electrical characteristics relevant to the design.
