MPQ6541AGQKTE-AEC1-P

Overview

The MPQ6541AGQKTE-AEC1-P is a three-phase power stage motor driver from Monolithic Power Systems, designed for automotive applications. It integrates three half-bridges with six N-channel power MOSFETs, capable of delivering an 8A continuous output current and supporting a supply voltage range of 4.75V to 40V. The device operates at a switching frequency of 2MHz and features a TQFN-26 (6mm x 6mm) package. It holds AEC-Q100 Grade 1 certification and functions within 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 support 100% duty cycle operation
• Includes independent high-side and low-side inputs for flexible control interface configurations
• Features integrated bidirectional current sampling amplifiers for precise motor current monitoring
• Provides comprehensive protection mechanisms including over-current, over-voltage, under-voltage lockout, and thermal shutdown

Applications

• Automotive LiDAR systems requiring qualified motor drivers
• Brushless DC (BLDC) motor control in automotive environments
• Multi-phase motor drive stages in automotive electronics

Procurement Notes

Verify the specific suffix 'P' indicates the tape-and-reel packaging configuration when placing orders. Confirm that the component meets AEC-Q100 Grade 1 requirements for your target automotive application. Ensure compatibility with the independent HS/LS input logic levels required by this variant. Check lead times as automotive-grade components may have extended manufacturing cycles.

Selection Notes

Select this part if your design requires independent high-side and low-side inputs rather than PWM/ENBL signals. It is suitable for BLDC motors needing up to 8A continuous current. Consider the 2MHz switching frequency for EMI management. Verify that the TQFN-26 footprint fits your PCB layout constraints and thermal dissipation needs.

Part Context

This component belongs to the MPQ6541-AEC1 family of automotive-grade motor drivers. It serves as the enhanced variant offering independent HS/LS inputs, distinguishing it from the standard MPQ6541-AEC1 which uses PWM/ENBL inputs. Both variants share identical electrical performance and safety features, providing flexibility for different controller architectures.

Replacement Considerations

MPQ6541AGQKTE-AEC1-Z is a compatible alternative within the same family, differing primarily in its PWM/ENBL input configuration instead of HS/LS inputs.
