MIC4607A-1YML-TRVAO

Overview

The MIC4607A-1YML-TRVAO is an 85V three-phase MOSFET gate driver IC manufactured by Microchip Technology. It features adaptive dead-time control, shoot-through protection, and overcurrent protection with blanking time insertion. The device supports independent high-side and low-side inputs or a single PWM input for internal generation of drive signals. It includes a high-voltage internal bootstrap diode for self-bootstrapping the high-side gate drive capacitor. The driver provides fast propagation delay of 35ns and rise/fall times of 20ns for a 1nF capacitive load. It operates within a junction temperature range of -40°C to +125°C and is housed in a 28-pin 4mm x 5mm VQFN package with wettable flanks.

Feature Summary

• Adaptive dead-time and shoot-through protection ensure safe switching in three-phase applications.
• Integrated overcurrent protection with programmable blanking time enhances system reliability.
• Fast propagation delay and edge rates support high-frequency motor control operations.
• Internal bootstrap diode simplifies high-side gate drive circuit design.

Applications

• Three-phase and BLDC motor drivers
• Three-phase inverters
• Automotive BLDC motor applications

Procurement Notes

Verify the complete part number MIC4607A-1YML-TRVAO against official Microchip documentation to confirm the specific tape-and-reel packaging and AEC-Q100 automotive qualification status. Ensure compatibility with your PCB footprint for the 28-pin VQFN package. Cross-reference the revision history in the datasheet to account for any updates in electrical characteristics or pinout definitions before finalizing procurement.

Selection Notes

Select this component for applications requiring robust three-phase gate driving with integrated protection features. It is suitable for designs needing adaptive dead-time management to optimize efficiency and prevent cross-conduction. Consider the 85V supply voltage limit and the 1A output current capability when sizing external components. Verify that the thermal performance of the VQFN package meets the requirements for the intended operating environment and power dissipation levels.

Part Context

The MIC4607A series belongs to Microchip's family of three-phase MOSFET drivers designed for high-performance motor control. This specific variant, MIC4607A-1YML-TRVAO, is optimized for automotive and industrial applications requiring high reliability and compact form factors. It integrates multiple protection functions typically found in discrete solutions, reducing bill-of-materials count and board space while maintaining high switching speeds and noise immunity.

Replacement Considerations

Direct replacements must match the 85V rating, three-phase configuration, and 28-pin VQFN package. Verify functional equivalence regarding adaptive dead-time and protection features. Check for AEC-Q100 compliance if used in automotive contexts. Consult Microchip's official substitution guide for validated alternatives.
