1 DN000 Design note A high power stepper motor driver Designs from our labs describe tested circuit designs from ST labs which provide optimized solutions for specific applications. For more information or support, visit By Thomas Hopkins Dennis Nolan L0 LE Main components Current Controller For Stepping Motors High-voltage half bridge driver Specification Circuit description phase bipolar motor driver Full Step, half Step and microstep operation Output current >A* Motor voltage >0V * When the voltage or current is outside of the capabilities of the integrated driver ICs, discrete power devices can be used with integrated gate driver ICs and a current controller to implement a high power stepper motor driver. The circuit shown in Figure can easily be adapted to a wide range of current and voltage levels to meet the application requirements. The power stage is a dual full H-bridge configuration needed for a -phase bipolar stepper motor. Each leg of the bridge is implemented using discrete power MOS devices and an LE half bridge gate driver IC. The LE was selected for its logical compatibility with the L0 current controller and its built-in dead time to prevent cross conduction in the bridge. The test board included a MOS device rated at 0A and 00V in a TO-0 package. By changing the power MOS devices, the design can be modified for a wide range of voltage and current. The series gate resistors may need to be changed for different power MOS devices and can be selected to set the switching time of the power MOS. The test board used power transistors in the TO-0 package that allows a very simple heat sink configuration. For moderate power levels, in the range of to 0A, it s possible to build a very compact drive using power transistors in DPAK with just the copper area on the PCB for heat sink and the LED and L0D in SO package. * Depends on selected power MOS device.

5 The L0 regulates the motor current by comparing the voltage across sense resistors R0 and R to the voltage references. When the voltage across the sense resistor exceeds the reference voltage, the L0 turns off the output and allows the current to recirculate until the oscillator turns the bridge back on. The value of the sense resistor and the reference voltage set the peak motor current according to the equation: I peak = V REF / R sense For a typical application, the value of R sense is chosen so that the voltage across the sense resistor at maximum motor current is between 0. and 0. V. Inputs - control the phases of the bridge. If an input is high, the high side transistor of the corresponding half bridge will be turned on. If the input is low, the low side transistor of the corresponding half bridge will be turned on. Since the L uses a bootstrap diode to power the high side gate driver, operation at 00 duty cycle on the high side is not possible. However, the L0 ANDs the PWM signal to control the current with the logic input so that, as long as current is being regulated, the high side is switched at the chopping frequency and the bootstrap is always refreshed. ENA and ENB are the enable for the bridges. When ENA or ENB is low, all four transistors of the corresponding bridge are turned off. Jumper WJ is used to select fast or slow decay mode. Connector J is compatible with the PractiSP evaluation system. The board may be controlled from the PractiSP interface by selecting the L0 in the device list. Variations The LE was selected for its logic compatibility with the L0 and that it included dead time control. Other gate drivers that may be used are the L90, L9, L9 and L9 that are also logic compatible with the L0.
