ST powerSTEP01系统级封装(SIP)步进马达驱动方案
ST公司的powerSTEP01是集成了8路16 mΩ MOSFET的系统级封装(SIP)步进马达驱动器,包括有SPI可编程控制器,提供马达群数字控制.器件工作电压高达85V,最大输出电流10A,多达1/128微步距,具有SPI接口,过流保护和超温保护,主要用在大功率双极步进马达如舞台照明,监测系统,纺织和缝纫机,PCB贴片机.本文介绍了powerSTEP01主要特性,框图和典型应用电路,以及演示板EVLPOWERSTEP01主要特性和主要指标,电路图和材料清单与PCB主要元件布局图.
The powerSTEP01 is a a system-in-package integrating 8 N-channel 16 mΩ MOSFETs for stepper applications up to 85 V with a SPI programmable controller, providing fully digital control of the motion through a speed profile generation and positioning calculations. It integrates a dual low RDS(on) full bridge with embedded non-dissipative overcurrent protection.
