Maxim MAX17523A 4.2V-36V 1A电流限制器解决方案

Maxim公司的MAX17523/MAX17523A是业界最小的和强健的集成系统保护解决方案,可调过压和过流保护器件非常适合正和负输入电压故障高达±40V的系统保护,具有190mΩ(典型值) RON集成的FET. MAX17523的可调过压范围在6V和36V之间,而可调欠压范围在4.4V和24V之间.过压锁住(OVLO)和欠压锁住(UVLO)阈值是33V(典型值),而目前的内部UVLO阈值为19V(典型值). MAX17523/MAX17523A可编程电流限值保护高达1A.器件可设定自动重试,栓锁或连续故障响应当过流情况发生时.一当电流达到阈值, 在设定自动重试模式时,MAX17523/MAX17523A在21ms消隐时间后就关断,并在重试周期保持关断.当设定栓锁模式器件在消隐时间后就关断.当设定连续模式器件就连续限制电流. MAX17523/MAX17523A还具有反向电流和热关断保护特性.器件采用小型16引脚3mmx3mm TQFN封装,工作温度-40°C 到 +125°C.主要用在传感器系统,条件监视,工作传感器,过程分析,生产过程用检测仪以及称重和配料系统.本文介绍了MAX17523A主要优势和特性,功能框图, 典型应用电路图以及评估板MAX17523A EVK主要特性,电路图,材料清单和PCB设计图.
