MP6532

5V to 60V, Three-Phase Brushless

DC Motor Pre-Driver

DESCRIPTION

FEATURES

The MP6532 is a gate driver IC designed for

three-phase brushless DC motor driver

applications. It is capable of driving three half

bridges consisting of six N-channel power

MOSFETs up to 60V.

•

Wide 5V to 60V Input Voltage Range

Built-in Hall Sensor Inputs and 120°

Commutation Logic

Charge Pump Gate Drive Supply

Bootstrap High-Side Driver with Trickle-

Charge Circuit Supports 100% Duty Cycle

Operation

Low-Power Sleep Mode

Programmable Short-Circuit Protection

Over-Current Protection

•

The MP6532 integrates a regulated charge pump

to generate gate drive power, and uses a

bootstrap capacitor to generate a supply voltage

for the high-side MOSFET driver. An internal

trickle-charge circuit maintains sufficient high-

side gate driver voltage even when an output is

operated at 100% duty cycle

•

Adjustable Dead-Time Control to Prevent

Shoot-Through

•

Thermal Shutdown and UVLO Protection

Fault Indication Output

Thermally Enhanced Surface-Mount Package

Internal

protection

features

include

programmable short-circuit protection, over-

current protection, adjustable dead-time control,

under-voltage lockout (UVLO), and thermal

shutdown.

APPLICATIONS

•

Three-Phase Brushless DC Motors and

Permanent Magnet Synchronous Motors

Power Drills

Impact Drivers

E-Bike

The device integrates 120° commutation using

three Hall sensor inputs. The PWM, DIR, and

nBRAKE inputs are used to control motor speed,

direction, and braking.

•

The MP6532 is available in 28-pin, 9.7mm ×

6.4mm TSSOP and 4mm x 4mm QFN packages

with an exposed thermal pad.

All MPS parts are lead-free, halogen-free and adhere to the RoHS directive.
