【应用】低压差线性稳压器A6250用于便携式血糖仪电源,1.5-10V宽输入电压、3μA超低静态功耗
便携式血糖仪主要用于家庭医疗领域,主要由MCU、采集单元、电源构成,该设备采用电池供电,对内部器件功耗要求较高,一般都是采用低功耗LDO给MCU和采集单元供电,同时要求体积小、输出电压精度高。
针对便携式血糖仪内部MCU和采集单元的电源设计,推荐AIT创瑞科技的低压差线性稳压器A6250,输入电压为1.5-10V,输出电压可选1.2V-6V,还可以输出固定电压,以0.1V为步进,支持输出电流250mA ,以下是A6250典型电气参数。
便携式血糖仪通常采用电池供电,电压最高能达到6V左右,A6250常规输入电压达到8V,极限可以达到10V,输出电压1.2-6V,可以满足血糖仪内部MCU、采集等不同单元的供电需求。为延长血糖仪电池寿命,要求内部器件静态功耗尽量低,A6250具备超低的静态工作电流3μA,可以提高电池利用率,延长血糖仪单次电池使用周期。
血糖仪测量精度与采集单元供电精度相关,A6250的输出电压精度常规可以达到2%,还可以提供1%版本,满足采集单元对电压精度的需求,提高工作稳定性。便携式血糖仪体积小,内部空间有限,A6250具有SOT23-3小尺寸封装,应用电路只需要1μF滤波电容,可以减小PCB面积,以下是A6250的引脚示意图和应用电路。
