Device Overview
MPQ6541GQKTE-AEC1-Z is the automotive-qualified MPQ6541-AEC1 three-phase BLDC power stage from MPS. It integrates three half-bridges built from six N-channel MOSFETs, current-sense amplifiers, gate-drive supplies, and PWM/ENBL control in a wettable-flank TQFN-26 package.

Engineering Selection Notes
The 8 A value is a continuous-current capability only when PCB copper and thermal conditions support it. The 12 A value is a separate one-second peak condition. Motor phase current, ambient temperature, switching loss and board thermal resistance therefore determine how much of the headline current can be used continuously.
The exact MPQ6541-AEC1 interface uses PWM and ENBL inputs. The related MPQ6541A-AEC1 uses separate high-side and low-side inputs, so those family variants should not be treated as control-interface equivalents without firmware and pinout review.
The integrated charge pump supports 100% duty-cycle operation, which is useful when phase voltage must approach the supply rail. This does not remove the need to verify switching frequency, dead-time behavior, current-sense headroom and motor inductance for the intended control scheme.
