MP6651

2A, Single-Phase BLDC Driver

with Integrated Hall Sensor

DESCRIPTION

FEATURES

The MP6651 is a single-phase brushless DC

(BLDC) motor driver with integrated power

MOSFETs and a Hall-effect sensor. The input

voltage (V_IN) is between 3.3V and 18V.

•

On-Chip Hall Sensor

Wide 3.3V to 18V Operating Input Voltage

(V_IN) Range

2A Continuous Current with QFN-10

Package

1.5A Continuous Current with SOIC-8 SL

Package

Integrated Power MOSFETs

Configurable Starting Duty Cycle

Configurable Min Output Duty Cycle

Configurable Soft-On/Off Commutating

Angle (Max: 45°)

Configurable Hall Offset Angle (Max: ±45°)

4-Step Configurable Current Limit

2kHz to 100kHz PWM Input Range

2.4s to 19.2s Configurable Soft-Start Time

Fixed 27kHz Output Switching Frequency

(f_SW)

Rotor Lock Protection with Auto-Recovery

Thermal Protection with Auto-Recovery

Built-in Input OVP and UVLO with Auto-

Recovery

Available in SOIC-8 SL and QFN-10

(2mmx3mm) Packages

•

The motor speed is controlled by the input

PWM duty from PWM pin. The MP6651

features a configurable soft-on/off commutation.

It also features a Hall offset angle across the

full speed range to flexibly optimize low-speed

and high-speed performance.

•

The MP6651 provides rotational speed

detection. The rotational speed detector (the

FG/RD pin) is an open-drain output. It outputs a

high or low voltage relative to the internal Hall

comparator’s output. The FG/RD pin can also

configured for rotor lock indication.

•

Robust protections include input over-voltage

protection (OVP), under-voltage lockout (UVLO),

locked rotor protection, over-current protection

(OCP), and thermal shutdown protection.

•

The MP6651 is available in a straight-lead

SOIC-8 package and a QFN-10 (2mmx3mm)

package.

•

APPLICATIONS

•

High-Current Cooling Fans

Personal Computers or CPU Fans

Single-Phase BLDC Fans
