Stepper Motor Driver Schematic 8.2.2.1 Design Requirements Figure 11 shows an implementation of TPL7407L for driving a uniploar stepper motor. The unconnected input channels can be used for other functions. When an input pin is left open the internal 1 M Ω pull down resistor pulls the respective input pin to GND potential. For higher noise immunity use an external short across an unconnected input and GND pins. The COM pin must be tied to the supply of whichever inductive load is being driven for the driver to be protected by the free-wheeling diode. Whenever a Zener diode is used between Vcom and the motor supply, the Vcom pin will slew from the coil supply to a voltage that is the sum of the Zener voltage and the coil supply when there is a flyback event. Depending on the coil inductance & resistance, this can be very rapid. Whenever the COM pin may experience a slew rate greater than 0.5 V/µs a capacitor must be added to limit the slew to < 0.5 V/µs. See Power Supply Recommendations for further explanation. 8.2.2.2 Detailed Design Procedure Refer to Design Requirements. 8.2.2.3 Application Curves Refer to Thermal Characteristics.
