STK6103

Specifications

Maximum Ratings at Ta = 25°C

Allowable Operating Ranges at Ta = 25°C

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 (Vref

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 Vref

switch to PWM drive for high-efficiency motor speed

variation.

• Normal and reverse revolution select function.

• Start/stop and brake functions.

• Current limiter function.
