MP6652

18V, Single-Phase BLDC Motor Driver

with Integrated Hall Sensor

DESCRIPTION

FEATURES

•

On-Chip Hall Sensor

Wide 3V to 18V Operating Input Voltage

(V_IN) Range

The MP6652 is a single-phase brushless DC

(BLDC) motor driver with integrated power

MOSFETs and a Hall-effect sensor. It drives a

single-phase brushless DC fan motor, with an

input voltage (V_IN) range of 3V to 18V.

•

Integrated Power MOSFETs: Total 850mΩ

High-Side MOSFET (HS-FET) and Low-

Side MOSFET (LS-FET)

The MP6652 controls the rotational speed

through the pulse-width modulation (PWM)

signal on the PWM pin. The device features a

built-in, configurable curve speed function that

is ideal for cooling fan applications, which

require flexible speed curve control.

•

Configurable Starting Duty Cycle

Rotational Speed Indicator FG Signal

Rotor Lock Protection Fault Indication

1kHz to 100kHz Pulse-Width Modulation

(PWM) Input Frequency Range

Fixed 27kHz Output Switching Frequency

(f_SW)

•

The MP6652 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. Higher speeds produce

higher frequency signals.

Configurable Soft-On/Off Commutation

Angle (Max 90°)

•

Configurable Soft Start (SS)

Rotor Lock Protection with Auto-Recovery

FG Outputs 0.5x, 1x, or 2x Original Hall

Frequency

Full protections include input over-voltage

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

locked rotor protection, and thermal shutdown.

•

Thermal Protection with Auto-Recovery

Built-In Input Over-Voltage Protection (OVP)

and Under-Voltage Lockout (UVLO) with

Auto-Recovery

Available in TSOT23-6-SL and TSOT23-6-L

Packages

The MP6652 is available in a TSOT23-6-SL

package and a TSOT23-6-L package.

•

APPLICATIONS

•

CPU and GPU Fans

Brushless DC (BLDC) Motors

Cooling Fans
