MP9517

Single-Phase, BLDC, Motor Driver

with Integrated Hall Sensor

DESCRIPTION

FEATURES

The MP9517 is a single-phase, brushless DC

motor driver with integrated power MOSFETs

and a Hall-effect sensor. The IC has a 3.3V to

18V input voltage range and input line reverse

voltage protection.



Embedded Hall Sensor with High Sensitivity

Wide 3.3V to 18V Operating Input Range

2A Overload Current Limit

Integrated Power MOSFETs: Total 1.02Ω

(HS + LS)



Winding BEMF and Current Zero-Crossing

with the Same Phase

Soft-On/Off Phase Commutation

Rotational Speed Indicator (FG) Signal

2kHz to 100kHz PWM Input Frequency

Range

Fixed 26kHz Output Switching Frequency

Input Line Reverse Voltage Protection

(RVP)

Rotor Deadlock Protection and Automatic

Recovery

The MP9517 controls the rotational speed

through the PWM signal on the PWM pin, with a

2kHz to 100kHz PWM frequency range. The

MP9517 has a rotational speed detection feature

on the FG pin, an open-drain output.



To reduce fan driver audible noise and power

loss, the MP9517 features soft-on/off phase

commutation, and automatic control for winding

BEMF and current zero-crossing with the same

phase.



Full protection features include input over-

voltage protection (OVP), under-voltage lockout

(UVLO), rotor deadlock protection, thermal

shutdown, and input reverse protection.



Thermal Protection and Automatic Recovery

Built-In Input OVP, UVLO, and Automatic

Recovery

Available in TSOT23-6-SL or TSOT23-6-L

Packages



The MP9517 requires a minimal number of

external components to reduce solution cost. It

is available in a TSOT23-6-SL and TSOT23-6-L

package.

APPLICATIONS



CPU Fan for Personal Computers or

Servers



Brushless DC Motors
