Description: A typical application example is presented, demonstrating the SAA1042 12V stepper motor drive configuration. The phase winding current is set at 200mA. According to RB Figure 5-10, a resistor value of RE = 56kΩ is selected. This resistor is connected to the output of the NAND gate MC14007. The clock signal is generated by the MC14046 and MC14024 PLL frequency synthesizer, producing a stepping clock frequency ranging from 12.5 to 500Hz, which allows for seven gear selections.
The SAA1042 stepper motor driver operates with a supply voltage of 12V, making it suitable for applications requiring precise control of motor positioning. The selection of a 200mA phase winding current indicates that the motor is designed to operate efficiently at this current level, ensuring optimal performance while minimizing power consumption and heat generation.
The resistor RE, valued at 56kΩ, plays a crucial role in setting the appropriate biasing conditions for the driver circuit, ensuring stable operation and preventing excessive current draw that could lead to overheating or damage. The integration of the NAND gate MC14007 facilitates logic operations essential for controlling the stepper motor's direction and stepping sequence.
