STK6103
DC 3-phase Brushless Motor Driver
(Output Current 3A)
Overview
The STK6103 is a hybrid IC incorporating a 3-phase
brushless motor controller and driver into a single
package, on the Sanyo IMST (Insulated Metal Substrate
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.

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.
