STK6103 Datasheet (Sanyo Semicon Device) - DC 3-phase Brushless Motor Driver

STK6103, DC 3-phase Brushless Motor Driver

of Operation The DC 3-phase brushless motor generally uses a permanent magnet for the rotor and places the stator coil around it.

When the rotor and stator coil are excited, magnetic force is generated between the poles, which is used for revolution torque.

For efficient revolution it is necessary t

Ordering number : EN4290A Thick-film Hybrid IC STK6103 DC 3-phase Brushless Motor Driver (Output Current 3A) Overview Package Dimensions The STK6103 is a hybrid IC incorporating a 3-phase unit: mm brushless motor controller and driver into a single package, on the Sanyo IMST (Insulated Metal Substrate 4130 Technology) substrate.

Revolution speed is controlled through the DC voltage level (Vref1) external input and PWM control of motor phase winding current.

The driver is MOSFET to minimize

STK6103 Features

* The output driver transistor is MOSFET for low power loss (half that of a bipolar transistor) and reliable handling of high-output current (rush current).

* Variation in Vref1 level causes the driver transistor to switch to PWM drive for high-efficiency motor speed variation.
