带NTC温度检测的电池制作说明
制作：版本： 日期： 2012.03.21
1.文档说明：
本文档是针对我司MT6575项目，配带NTC温度检测电池制作说明。在这以前我司的项目配用的电池都是不带NTC检测的，为了让提高智能机检测电池电量的准确性，必须获得电池的温度，通过软件的运算可以让手机能够准确的显示当前电池的百分比。我司要求MT6575平台的项目都要增加NTC温度检测，该文档就是说明和以前电池内部短路不同的地方。
2.引脚定义：
带NTC温度检测的电池一般要有3个引脚，这3个引脚的功能分别是电池正极、电池负极、电池的ID引脚定义顺序要根据不同项目有所不同，要具体确认。
3.电池内部接线：
带NTC的电池和一般的电池最大的不区别就是ID Pin和电池的负极之间加一个NTC器件，这个器件我司指定使用47K的，当然不能用固定电阻替代，因为NTC的阻值是随温度变化而变化的，只有这样才能检测到电池的实际温度。
4.NTC的选型：
我司目前验证过的NTC型号为 顺络的SDNT1005X473F4100FTF（联系方式：杨蕊:[1**********]，
，请务必使用这个料。以后等验证新的代用料在做更新。在电池021-33674648，）
打样期间要将样品寄到我司验证，验证合格后才能批量生产。

The solderability of the external electrode may be deteriorated if packages are stored where they are exposed to high humidity. Package must be stored at 40℃ or less and 70% RH or less.
The solderability of the external electrode may be deteriorated if packages are stored where they are exposed to dust of harmful gas (e.g. HCl, sulfurous gas of H2S)
Packaging material may be deform-ed if package are stored where they are exposed to heat of direct sunlight.
Solderability specified in Clause 5.4.6 shall be guaranteed for 3 months from the date of delivery on condition that they are stored at the environment specified in Clause 3 .For those parts, which passed more than 3 months shall be checked solder-ability before use.
