MPQ6614GDE-AEC1-P

Overview

The MPQ6614GDE-AEC1-P is an H-Bridge DC motor driver from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 5 V to 35 V and delivers continuous output currents of 1.5 A per channel. The device features a low quiescent current of 1.4 mA to 1.8 mA and supports PWM frequencies up to 50 kHz. It functions reliably across an extended temperature range from -40°C to +125°C and dissipates up to 1.78 W of power. The component is housed in a compact QFN-8 surface-mount package.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Integrated H-Bridge topology for bidirectional motor control
• Low quiescent current operation for energy efficiency
• Extended thermal performance suitable for harsh environments

Applications

• Automotive seat adjustment motors
• Power window actuators
• HVAC blower fan control
• Sunroof drive mechanisms

Procurement Notes

Verify the specific suffix 'AEC1' confirms automotive grade qualification and lead time requirements against official MPS documentation. Confirm the QFN-8 package wettable flanks or standard termination type matches PCB design constraints. Ensure input voltage does not exceed 35 V during load dump conditions to prevent damage.

Selection Notes

Select this component when a single-chip solution for bidirectional DC motor control is required in space-constrained automotive designs. The 1.5 A rating suits small to medium loads like wipers or fans. Consider the QFN-8 footprint for board density. Verify thermal management capabilities if operating near the maximum power dissipation limit of 1.78 W.

Part Context

This part belongs to the MPQ6614 series of half-bridge drivers optimized for automotive use. It integrates high-side and low-side MOSFETs into a single monolithic structure. The series focuses on simplifying motor driver implementation by reducing external component count while maintaining robust protection features typical of modern PMIC solutions.

Replacement Considerations

Consult official MPS substitution guides for direct equivalents. Generic replacements may lack AEC-Q100 certification or matching pinout compatibility. Verify that any substitute maintains the 35 V rating and 1.5 A current capacity without altering the control interface logic.
