infineon公司的步进马达驱动扩展板采用通用6A H桥IFX9201SG和XMC1300 AB步微控制器(MCU). IFX9201SG设计用于DC马达或其它感性负载,它的输出脉宽调制频率高达20kHz,每个开关在Tj=25℃时的RDSon为100 mΩ,逻辑输入和3.3V和5.0V TTL/CMOS兼容,具有低待机电流,斩波电流限制,具有闩锁行为的短路关断和超温关断,而XMC1300微控制器(MCU)是基于ARM Cortex-M0处理器核的XMC1000系列MCU,具有实时马达控制和数字功率转换,以及用于LED照明应用的外设.XMC1300 MCU是高性能32位ARM Cortex-M0 CPU,单周期32位硬件乘法器,操作系统支持系统计时器(SysTick),具有超低功耗和嵌套向量中断控制器(NVIC),MATH协处理器(MATH),用于三角算法的CORDIC单元和除法单元,片上存储器包括有8KB ROM,16KB高速SRAM和高达200KB闪存程序和数据存储器,以及USIC,UART,双SPI和四SPI,IIC,IIS和LIN接口通信外设等.本文介绍了IFX9201+ XMC1300主要特性,框图,多种H桥应用电路图以及步进马达驱动扩展板框图和应用框图,电路图和PCB设计图.
The IFX9201SG is a general purpose 6 A H-Bridge, designed for the control of DC motors or other inductive loads.
The outputs can be pulse width modulated at frequencies up to 20kHz. PWM/DIR control reduces the number ofPWM capable pins needed on the microcontroler side.
For load currents above the current limitation threshold (8A typ.) the H-Bridge goes into chopper current limitationmode. It is protected against short circuits and overtemperature and provides extensive diagnosis via SPI or basicfeedback via error flag. Open load can be detected when the bridge is disabled or during PWM operation ofinductive loads.
The robust PG-DSO-12-17 package provides excellent thermal capabilites due to the thick copper heat slug.
Thanks to the protruding edges of the heatslug the package is well suited for automatic optical solder inspection.
The IFX9201SG is not qualified and manufactured according to the requirements of Infineon Technologies withregards to automotive and/or transportation applications. For automotive applications please refer to theTLE9201SG.
IFX9201SG主要特性:
• RDSon of 100 mΩper switch typ. at Tj=25℃
• Logic inputs 3.3 V and 5.0 V TTL/CMOS-compatible
• Low standby current
• Chopper current limitation
• Short circuit shut down with latch behavior
• Overtemperature shut down with latch behavior
• VS undervoltage shutdown
• Open load detection in ON and OFF state
• Detailed SPI diagnosis or simple error flag
• Green product (RoHS compliant)
