MPQ6541GQKTE-AEC1-P

Overview

The MPQ6541GQKTE-AEC1-P is a three-phase brushless DC motor driver from Monolithic Power Systems, designed for automotive applications with AEC-Q100 Grade 1 qualification. It integrates three half-bridges of N-channel power MOSFETs, pre-drivers, gate drivers, and current sense amplifiers. The device operates within a supply voltage range of 4.75V to 40V, delivering an 8A continuous output current per phase. Key electrical parameters include a 2MHz switching frequency, 15mΩ MOSFET on-resistance, and 4mA quiescent current. It supports PWM and ENBL inputs, features a TQFN-26 (6mmx6mm) package, and functions across a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates three half-bridges with internal charge pump and trickle charging circuitry to enable 100% duty cycle operation
• Includes automatic synchronous rectification and integrated bidirectional current sampling amplifiers for precise control
• Provides comprehensive protection mechanisms including over-current protection, under-voltage lockout, and thermal shutdown

Applications

• Automotive LiDAR systems requiring qualified motor drivers
• Three-phase BLDC motor control in automotive environments
• General automotive motion control applications

Procurement Notes

Verify the specific suffix 'E' indicates the enhanced or specific variant configuration against the official datasheet. Confirm that the 'P' suffix denotes the standard reel packaging format as listed by distributors. Ensure the component meets the required AEC-Q100 Grade 1 reliability standards for your target automotive application before finalizing procurement.

Selection Notes

Select this component when a fully integrated, automotive-grade solution for three-phase BLDC motors is required. It is suitable for designs needing PWM and ENBL input interfaces rather than independent HS/LS inputs. Consider its 8A continuous current capability and 2MHz switching frequency for efficient power management in space-constrained automotive modules.

Part Context

This part belongs to the MPQ6541 family of automotive motor drivers. It is functionally similar to the MPQ6541A-AEC1 but differs in input interface; the MPQ6541 variant uses PWM and ENBL inputs, whereas the MPQ6541A uses separate HS and LS inputs. Both share identical power stage characteristics and protection features.

Replacement Considerations

MPQ6541AGQKTE-AEC1-Z is a verified substitute offering equivalent functionality with different packaging options such as cut tape or Digi-Reel.
