Additional preview pages of the STK6103 datasheet.

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.

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. Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply.
