GE产品说IC693MDL390CA
IC693MDL390CA采用MSP430主控MCU和DRV8871电机驱动芯片结合的系统结构,如图1所示。系统利用MSP430的片上ADC采集NTC热敏电阻两端的电压,实现低成本的温度测量功能。另外,主控MCU在输出可调占空比的PWM波形的同时,预留了I2C通信接口,主机CPU可以给MSP430下达控制命令和读取温度、转速、故障状态等信息。通过在散热系统中加入温度测量反馈,可根据待散热对象的温度情况,实时控制风扇的转速,取代单一固定转速的风扇散热系统,达到的节能效果。同时,可以在风扇发生故障失效或者温度过高时,做出状态预警和保护处理。其中,DRV8871电机驱动芯片,大支持3.6A峰值电流,6.5V到45V的宽供电范围,集成过流保护、过温保护和休眠模式等功能。
