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 circuit loss and handle high-output current (rush current) demands. [STK6103] Applications • PPC and LBP drum motors • Air conditioner fan motors 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. • Normal and reverse revolution select function. • Start/stop and brake functions. • Current limiter function.

No. 4290- 3/11 STK6103 Sample Application Circuit Description 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 to know precisely where the rotor pole is in relation to the stator pole. In the brushless motor Hall devices and Hall ICs are.
