MP6616A

18V, 2A, Single-Phase BLDC Motor Driver

with an Embedded Hall-Effect Sensor and

Closed/Open-Loop Speed Control

DESCRIPTION

FEATURES

The MP6616A is a single-phase brushless DC

(BLDC) motor driver with an embedded Hall-

effect sensor and integrated power MOSFETs.

•

2mT Minimum Sensitivity Embedded Hall-

Effect Sensor

3.3V to 18V Operating Input Voltage (V_IN)

Range

•

It can achieve up to 2A of output current (I_OUT

)

across a 3.3V to 18V input voltage (V_IN) range.

•

2A Continuous Output Current (I_OUT)

100mΩ Integrated Power MOSFETs

Configurable Speed (40000rpm Max)

Configurable Minimum Speed and Starting

Duty

Closed-Loop or Open-Loop Speed Control

High-Speed Accuracy with Closed-Loop

Mode

Configurable Soft Commutation Angle (45°

Max)

Configurable Hall Offset Angle (±45° Max)

4-Step Configurable Current Limit (4A Max)

2kHz to 100kHz Pulse-Width Modulation

(PWM) Input Range

Configurable Soft-Start Time (t_SS)

27kHz Fixed Switching Frequency (f_SW)

Standby Mode

Locked Rotor Protection with Auto-

Recovery

Thermal Shutdown with Auto-Recovery

Built-In Input Over-Voltage Protection (OVP),

Under-Voltage Lockout (UVLO) Protection,

and Auto-Recovery

The MP6616A controls the motor speed with

closed-loop or open-loop control via the pulse-

width modulation (PWM) signal on the PWM

pin. The device features a configurable soft

commutation angle and Hall offset angle. The

hall offset angle can be flexibly optimized for

low-speed and high-speed performance across

the full speed range.

•

The MP6616A also features a rotational speed

detector (the FG/RD pin). FG/RD is an open

drain that outputs a high or low voltage relative

to the internal Hall comparator’s output.

•

Protection features include input over-voltage

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

protection, locked rotor protection, over-current

protection (OCP), and thermal shutdown.

•

The MP6616A is available in a QFN-10

(2mmx3mm) package.
