MIC4607A-2YML-TRVAO

Overview

The MIC4607A-2YML-TRVAO is an 85V three-phase half-bridge MOSFET gate driver manufactured by Microchip Technology. It integrates six drivers with adaptive dead time and shoot-through protection. The device operates on a supply voltage range of 5.25V to 16V, delivering 1A output current. Key electrical parameters include a propagation delay of up to 35ns, rise/fall times of 20ns for a 1nF load, and a maximum quiescent current of 600µA. It features TTL logic inputs and non-inverting configuration within a 28-pin VQFN package.

Feature Summary

• Integrates adaptive dead time control and shoot-through protection to prevent simultaneous high-side and low-side conduction.
• Features enhanced overcurrent protection with programmable blanking time insertion for robust fault handling.
• Includes a high-voltage internal bootstrap diode to facilitate high-side gate drive capacitor charging.
• Provides undervoltage lockout protection for both high-side and low-side outputs.

Applications

• Three-phase motor drives
• BLDC motor applications
• Three-phase inverters

Procurement Notes

Verify the specific suffix 'VAO' indicates automotive qualification compliance, specifically AEC-Q100 and AEC-Q006 standards as documented for this part number. Confirm the package type is the 28-pin VQFN (4mm x 5mm) with wettable flanks. Ensure the operating temperature range meets requirements for -40°C to +125°C junction temperature. Cross-reference the datasheet revision to ensure compatibility with design specifications.

Selection Notes
