MPQ6526GU-AEC1-Z

Overview

The MPQ6526GU-AEC1-Z is a Hex Half-Bridge Motor Driver from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It features six independent half-bridge outputs capable of delivering up to 900 mA output current per channel. The device operates within a supply voltage range of 7 V to 28 V and supports a switching frequency of 3 MHz. It utilizes serial input control for configuration and includes an operating supply current of 2.75 mA. The component is housed in a QFN-24 package and functions reliably across a temperature range of -40°C to +150°C.

Feature Summary

• Hex half-bridge architecture providing six independent motor driver channels
• Serial interface control for simplified system integration
• Automotive-grade reliability certified under AEC-Q100 standards
• Extended thermal performance supporting operation up to 150°C junction temperature

Applications

• Automotive seat adjustment systems
• Vehicle window and sunroof actuators
• HVAC blower motor control
• Power steering assist mechanisms
• Electronic locking and latching assemblies

Procurement Notes

Verify the specific suffix 'GU' against official MPS documentation to confirm package type and tape-and-reel specifications. Ensure the design accounts for the 24-pin QFN footprint and thermal pad requirements. Confirm that the 7V to 28V supply range aligns with the target vehicle electrical system. Validate that the serial communication protocol matches the host microcontroller capabilities before finalizing procurement.

Selection Notes

Select this component when a high-channel-count motor driver is required for automotive environments. The 900 mA per channel rating suits low-to-medium power actuator loads. Consider the 3 MHz switching frequency for efficient passive component sizing. The wide operating temperature range and AEC-Q100 certification are critical for meeting automotive durability standards compared to industrial-grade alternatives.
