MP6543C

22V, 1.2A Three-Phase BLDC Motor Driver

with Three Integrated Half-Bridges

DESCRIPTION

FEATURES

The MP6543C is a three-phase brushless DC

(BLDC) motor driver with three integrated half-

bridges, consisting of six N-channel power

MOSFETs, as well as six pre-drivers, two gate

driver power supplies, and three current-sense

amplifiers. Each half-bridge includes an enable

(EN) input and pulse-width modulation (PWM)

input. The MP6543C can achieve up to 1.2A of

continuous output current (I_OUT) across a 3V to

22V input voltage (V_IN) range.

•

3V to 22V Operating Input Voltage (V_IN)

Range

Three Integrated Half-Bridge Drivers

•

1.2A Continuous Output Current (I_OUT

110mΩ R_DS(ON)per MOSFET

Enable (EN) Input and Pulse-Width

Modulation (PWM) Input

)

•

3.3V, 100mA Built-In Low-Dropout (LDO)

Regulator

Internal Charge Pump for 100% Duty Cycle

Automatic Synchronous Rectification

Integrated Bidirectional Current-Sense

Amplifiers

Configurable Over-Current Protection

(OCP)

Under-Voltage Lockout (UVLO) Protection

•

The internal current-sense circuit does not

require a low-ohmic shunt resistor. Each half-

bridge has an independent ground pin (LSSA,

LSSB, and LSSC) that allows current to be

measured via an external shunt resistor. This

allows the MP6543C to be used for different

application requirements.

•

Thermal Shutdown

Available in a QFN-24 (3mmx4mm)

Package

An internal charge pump generates the gate

driver supply voltage for the high-side MOSFETs

(HS-FETs). A trickle-charge circuit maintains a

sufficient gate driver voltage for 100% duty cycle

operation.

APPLICATIONS

•

Three-Phase Brushless DC (BLDC) Motor

Drivers

Full protection features include configurable

over-current protection (OCP), under-voltage

lockout protection (UVLO), and thermal

shutdown.

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