TI TIDA－01227 15-70V步进马达控制参考设计
TI公司的参考设计TIDA-01227是用于双极应用的15-70V步进马达控制器,采用TI的DRV8711步进马达控制器,CSD17483F4 N-MOSFET以及MSP430G2553 MCU和LM5107与LM5017等器件,输入电压范围15V到70V,输出电流2A RMS,峰值电流3A,主要用在高速打印机和高速工业步进器.本文介绍了参考设计TIDA-01227主要特性和主要指标,框图,电路图,材料清单和PCB设计图.
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.
