UF2768

Preliminary

CMOS IC

THREE-PHASE SINE-WAVE

SENSOR-LESS FAN MOTOR

DRIVER

MSOP-10



DESCRIPTION

The UF2768 provides all the circuitry for sensor-less speed

control of three-phase brushless DC motor. The Sine-wave

Driver Method will be better low-noise. The controller functions

include start-up circuit, back-EMF commutation control, Pulse

Width Modulation (PWM) speed control, lock protection, and

thermal shutdown circuit.

DFN3030-10

The UF2768 is suitable for both game machine and CPU

cooler that need silent drivers.



FEATURES

* Three-Phase class sin wave driver method

* Three-Phase Full-Wave Sensor-Less Drive Method

* Adjustable Forced Commutation Frequency (for Start-up)

* Built-In External PWM Speed Control

* Built-In Quick Start Function

* FG (Rotation Speed Detection) Output

* Soft Switching Circuit (for Noise Reducing)

* Power Saving Function (PWM Duty Input is 0%)

* Built-In Lock Protection and Auto Restart Function

* Thermal Shutdown Circuit
