MPQ6528GVE-AEC1-Z

Overview

The MPQ6528GVE-AEC1-Z is a full-bridge gate driver IC designed for automotive applications, qualified under AEC-Q100 standards. It operates within a supply voltage range of 5 V to 60 V and supports synchronous N-channel MOSFET configurations. The device features two independent drivers with peak output currents of 800 mA source and 1 A sink. It utilizes a 28-VFQFN package (4x5 mm) with an exposed pad for thermal management. The operational junction temperature range spans from -40°C to +150°C, ensuring reliability in harsh environments.

Feature Summary

• Integrated charge pump provides self-powered high-side gate drive capability, maintaining sufficient voltage even at 100% duty cycle operation.
• Adjustable dead-time control mechanism prevents shoot-through conditions between upper and lower bridge MOSFETs.
• Includes comprehensive protection features such as over-temperature shutdown and under-voltage lockout for system safety.

Applications

• Brushed DC motor control systems
• Automotive ignition circuits
• Motion control actuators

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status according to manufacturer declarations. Confirm the 'AEC1' designation aligns with required automotive qualification grades. Ensure the 28-VFQFN footprint matches the PCB layout specifications. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when driving two half-bridges with N-channel MOSFETs in automotive environments requiring wide input voltage tolerance. Consider the 28-pin QFN package for compact designs needing efficient heat dissipation. Evaluate the adjustable dead-time feature if precise switching timing control is necessary to minimize cross-conduction losses.
