Product Summary
The STK65030II is a DC 3-phase Brushless Motor Driver 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. The applications of the STK65030II include PPC and LBP drum motors, Air conditioner fan motors.
Parametrics
STK65030II absolute maximum ratings: (1)Maximum supply voltage 1 VCC1 max No input signal: 50 V; (2)Maximum supply voltage 2 VCC2 max No input signal: 7 V; (3)Maximum output current IO max Position detect input signal cycle = 30 ms, PWM duty = 50%, operation time 1s: 5A; (4)Operating substrate temperature, TC max: 105℃; (5)Junction temperature, Tjmax: 150℃; (6)Storage temperature, Tstg: -40 to +125℃.
Features
STK65030II features: (1)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); (2)Variation in Vref1 level causes the driver transistor to switch to PWM drive for high-efficiency motor speed variation; (3)Normal and reverse revolution select function; (4)Start/stop and brake functions; (5)Current limiter function.
