MPQ6541-AEC1, MPQ6541A-AEC1

40V, 8A, Three-Phase Power Stage,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ6541-AEC1 and MPQ6541A-AEC1

are three-phase brushless DC (BLDC) motor

drivers with three integrated half-bridges. The

three half-bridges consist of six N-channel

power MOSFETs. The MPQ6541-AEC1 and

MPQ6541A-AEC1 also integrate six pre-drivers,

two gate driver power supplies, and three

current-sense amplifiers.

•

4.75V to 40V Operating Supply Voltage

Three Integrated Half-Bridge Drivers

8A of Continuous Output Current

MOSFET On Resistance: 15mΩ per FET

MPQ6541-AEC1: PWM and ENBL Inputs

MPQ6541A-AEC1: HS and LS Inputs

Internal Charge Pump Supports 100% Duty

Cycle Operation

•

Automatic Synchronous Rectification

Under-Voltage Lockout (UVLO) and Over-

Voltage Protection (OVP)

The MPQ6541-AEC1 has ENBL and PWM

inputs for each half-bridge; the MPQ6541A-

AEC1 has 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.

•

Thermal Shutdown Protection

Over-Current Protection (OCP)

Integrated, Bidirectional Current-Sense

Amplifiers

•

Available in a TQFN-26 (6mmx6mm)

Package with Wettable Flank

Available in AEC-Q100 Grade 1

The MPQ6541-AEC1 can deliver up to 12A of

peak current for 1 second, or 8A of continuous

current, 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.

APPLICATIONS

•

Brushless DC (BLDC) Motor Drivers

Permanent Magnet Synchronous Motor
