The MPQ6541-AEC1 is a three-phase brushless DC (BLDC) motor driver with three integrated half-bridges. The three half-bridges consist of six N-channel power MOSFETs. The MPQ6541-AEC1 also integrate six pre-drivers, two gate driver power supplies, and three current-sense amplifiers.
The MPQ6541-AEC1 integrates ENBL and PWM inputs for each half-bridge. The MPQ6541AAEC1 integrates separate high-side (HS) and low-side (LS) inputs. Otherwise, these parts are identical. References to the MPQ6541-AEC1 also apply to the MPQ6541A-AEC1, unless otherwise noted.
The MPQ6541-AEC1 can deliver up to 12A of peak output current (IOUT) for 1 second, or up to 8A of continuous IOUT, depending on thermal and PCB conditions. The device uses an internal charge pump to generate the gate driver supply voltage for the high-side MOSFETs (HS-FETs), and a trickle charge circuit that maintains sufficient gate driver voltage to operate at 100% duty cycle.
Internal safety features include thermal shutdown, under-voltage lockout (UVLO) protection, and over-current protection (OCP).
The MPQ6541-AEC1 is available in a TQFN-26 (6mmx6mm) package.

INTEGRATED DRIVERS VS. GATE DRIVERS FOR MOTOR DRIVINGWhen designing a motor control circuit, it is vital to determine how to deliver the high current required to drive the motor. Designers must choose whether to use monolithic integrated circuits that have internal power devices, or gate driver ICs and discrete external power MOSFETs. This article discusses the advantages and disadvantages of each approach and provides guidance on when to choose eit...
