MIC4607A-2YMLVAO

Overview

The MIC4607A-2YMLVAO is an 85V three-phase MOSFET driver designed for high-speed switching applications. It features adaptive dead-time control and anti-shoot-through protection to ensure reliable operation. The device provides fast propagation delays of 35ns and rise/fall times of 20ns for a 1nF capacitive load. It supports independent high-side and low-side inputs or a single PWM input, with TTL-compatible logic thresholds. Integrated features include overcurrent protection with blanking time, a bootstrap diode, and undervoltage lockout for both high and low sides.

Feature Summary

• Adaptive dead-time and anti-shoot-through protection prevent simultaneous conduction in half-bridge configurations.
• Integrated overcurrent protection with programmable blanking time safeguards against short circuits.
• High-speed switching capabilities with 35ns propagation delay and 20ns rise/fall times minimize switching losses.
• Robust output stage withstands battery faults, sub-ground ringing, and high dv/dt conditions.

Applications

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

Procurement Notes

Verify the complete part number MIC4607A-2YMLVAO against official Microchip documentation to confirm package type (VQFN) and tape-and-reel configuration. Ensure compatibility with AEC-Q100 automotive standards if required for your specific application environment. Cross-reference datasheet revision numbers to guarantee feature consistency.

Selection Notes

Select this component for applications requiring precise timing control in three-phase systems. The adaptive dead-time feature reduces power dissipation compared to fixed dead-time solutions. Verify that the gate drive supply voltage range (up to 16V) matches your MOSFET requirements. Consider the 28-pin VQFN package constraints for thermal management and PCB layout.
