* Description : Charger NTC Control
|
||
* NTC 支持 103 和 104 电阻，NTC 温度检测由软件通过 ADC 采集 NTC 引脚电压。
|
||
* 如果支持电量计温度检测线性化，支持电量计方案 103 的 NTC 需要并一个 8.2k
|
||
|
||
* 电阻（20uA 电流，103 NTC 需要串联 10k 电阻），104 的 NTC 并联 82k 电阻。
|
||
* 在使能充电前，软件先检测NTC 温度，如果 NTC 浮空，屏蔽 NTC 功能，
|
||
* 并锁定；如果 NTC 下拉到 0V，关闭充电和放电。NTC 保护后，软件关闭充电，
|
||
* 温度恢复正常并持续 250ms，再继续充电。
|
||
*
|
||
* Arguments : NTC_Protect_Type_e NTC_Type:Shield 、JEITA or IEC;Charge_sta:Charge or not
|
||
|

* Returns :NTC_Flag (0:Shield; 1:JEITA; 2:IEC)
