智能手机等移动设备的电池组中(锂离子电池)除了+端子与-端子之外，还有另外一个端子。那就是拥有T端子等名称的温度监测用端子，其内部搭载有NTC热敏电阻。在电池温度上升时，NTC热敏电阻温度也会随之上升，从而电阻值会下降，当超过上限充电温度时，充电控制IC将会停止充电。电池组内的保护IC会测量电池电压，从而防止过充电或过放电。在快速充电等要求充电控制更为精准的情况时，将会使NTC热敏电阻与充电控制IC进行连接，从而用于测量环境温度。

为此硕凯电子推出的一款测温型热敏电阻 SN0603X103F3380FB，可用于做精确温度检测，采用绿色环保的0603封装，无极性区分。可过卤素测试，具有可靠性高，机械应力强，耐环境性、耐变换电阻等优异性能。

该器件的阻值为10kΩ，R值误差精度可达±1%，B值为3380K（25/50°C）。另外，具有较高的耐环境适应性，工作温度范围为-40～+125℃。

SN0603X103F3380FB的特点：

R值（25℃）：10kΩ

R值误差：±1%

B值（25/50℃）：3380K±1%

热时间常数：5S

额定功率：100(mW)

工作温度范围：-40～+125℃

SN0603X103F3380FB的应用：

电池保护板

智能手机/平板

LED照明系统

微控制器

电池保护板主动均衡电路思考

单体电池保护板管理电路之间采用CAN总线进行通信和连接，CAN总线由4根信号线组成，GND_CAN为外部供电接口地线，CANL为CAN总线L信号，CANH为CAN总线H信号，+5VCAN为CAN模块+5V电源外部供电接口。odd代表奇数模块，even代表偶数模块。单体电池管理电路各自分别引出两根线与单体电池相连接，从而可实现随时从单体电池上将单体电池管理电路断开。
