【应用】圣邦微锂电保护芯片SGM41100A助力电容笔设计，待机功耗仅为1μA，采用UTDFN-1.5×2-6L小型封装
随着在线办公和网络学习的兴起，电容笔又掀起了一股热潮，电容笔主要分为两种，主动型和被动型电容笔，主动型电容笔内部有自己的电路，触摸屏通过接收电容笔发出的信号，来进行位置识别；而被动型电容笔内部是没有电路的，直接通过与触摸屏接触，来改变触摸屏的电容，主动型电容笔的精确度更高。
某客户打算研发一款主动型电容笔，由于是有源电路，内部就需要有电源供电，则需要用到可充电的锂电池，本文给客户推荐的是圣邦微的锂电池保护芯片SGM41100A，其主要优势有：
1、SGM41100A不需要外挂MOS，采用内置开关，外围仅需1C+1R两个元件，加上本身UTDFN-1.5×2-6L的小型封装，使得芯片在PCB节省空间上占了极大优势；
2、待机功耗仅为1μA，关断后的功耗仅为100nA，增强产品续航能力，十分契合电容笔应用；
3、SGM41100A支持多种电压的过压阈值保护和欠压阈值保护，便于设计。
封装示意图如下：

【选型】可用于双节锂电池充电电路中的过压保护芯片，40V高静态耐压能力可有效保护后级器件
在给双节锂电池充电时，常常会因为高静态电压导致电路故障或电池受损的问题，因此常需要在+5V输入电压后端接一个过压保护电路，此处我们为客户推荐一款过压保护芯片SGM40666AS/SGM40666BS。

【经验】解析基于SGM41524+SGM41101方案中电池防反接电路设计
笔者在LED手电设计中采用圣邦微充电芯片SGM41524+保护芯片SGM41101设计充电管理电路。相对于普通硅二极管防反接而言，Nmos+Pmos组成的电池防反接电路导通损耗更小。在实际设计中，此电路加上后级锂电池保护芯片SGM41101为产品提供多种保护方式，大大提高系统安全性。
