The TIDA-01227 reference design is a 15-V to 70-Vstepper motor controller for bipolar applications. Thedesign uses the following parts from Texas Instrument:
DRV8711 bipolar stepper motor, controller gate driver;
CSD19538Q3A 100-V, N-Channel NexFET™ powerMOSFETs;
CSD17483F4 30-V, N-ChannelFemtoFET™ MOSFET;
MSP430G2553 MCU;
LM5107100-V,1.4-A peak, half-bridge gate driver; andLM5017 12-V buck converter.
The focus of this designis to demonstrate the use of the DRV8711 steppermotor controller to control stepper motors at voltageshigher than 60 V. The DRV8711 operates at 12 Vwhile using additional circuitry to convert to highvoltagecontrol signals.
The TIDA-01227 design configures the DRV8711 device to control a bipolar stepper motor at voltagesabove the absolute maximum voltage of the DRV8711. This configuration is possible by adding aninterface between the DRV8711 controller and the CSD19538Q3A field-effect transistors (FETs). Theinterface converts lower-voltage signals to higher-voltage signals controlling the full-bridges. Thisconfiguration can be used in applications that require high-speed operation. Higher voltage allows thecurrent to change at a faster rate, which increases the motor speed. A high-speed printer is an example ofa typical application.
The reference design is composed of three main sections: the MCU, the power stage, and the powerconversion sections.
