【应用】顺络带你一文了解NTC热敏电阻基本参数及在手机、TWS耳机上的应用
热敏电阻(Thermistor)是一种温度敏感电阻器件,其电阻值会随着温度的变化而发生变化。因此热敏电阻可以分为两种类型:
正温度系数热敏电阻(PTC Thermistor-Positive Temperature Coefficient Thermistor)
负温度系数热敏电阻(NTC Thermistor-Negative Temperature Coefficient Thermistor)
NTC热敏电阻种类多样,以下列举常见类别
片式封装特点:体积小、多种规格、灵敏度高、可自动贴装。
常温型NTC热敏电阻
电阻变化原理:锰、钴、镍和铜等金属氧化物为主要材料。当温度低时,氧化物材料的载流子(电子和孔穴)数目少,其电阻值较高;随着温度的升高,载流子数目增加,其电阻值降低。
NTC热敏电阻基本电性参数
零功率电阻(R25):
(标称)零功率电阻值R25指在规定温度(25℃)测得的直流电阻值,由于自热导致的电阻值变化对于总的测量误差可以忽略不计。
B常数:
它是两个特定环境温度下的值计算出来的,如下面公式所示:
——T 和T0取绝对温度(K);
——一般对比温度为25℃/50℃,也有取25℃/85℃。
最大容许工作电流:
热敏电阻在静止空气中,周围环境温度为25℃,通过自身发热使其升温1℃的电流。
热时间常数:
热时间常数是热敏电阻在零功率状态下,当环境温度突变时,电阻体温度由起始温度变化到最终温度的63.2%时所需的时间。
耗散因子:
热敏电阻通过自身通电升温1 ℃所消耗的电功率。
额定功率:
热敏电阻从25 ℃升温100 ℃所消耗的电功率。
NTC热敏电阻主要作用
抑制浪涌电流:
温度检测及温度控制:
温度补偿:
顺络片式NTC热敏电阻应用案例举例(手机)
相机模组温度监控:
相机模组关键部位(如CMOS传感器)在工作时会产生大量热量,若温度过高会导致性能下降或故障。NTC热敏电阻可以监控这些关键部位温度变化,及时调整电路工作状态,提高模组的稳定性和可靠性。
闪光灯温度监控:
LED灯在使用过程中产生的热量会影响LED灯的亮度和寿命。为了防止温度过高对LED灯产生不良影响,需要使用NTC热敏电阻来限制LED灯的最大电流。
WiFi/Bluetooth温度监控:
WiFi/蓝牙电路模块在工作过程中会产生一定热量,尤其是在增大发射接收频率状态下。如果模块温度过高,可能会对电路元器件产生损害或导致性能下降。为了防止这种情况发生,可以使用NTC热敏电阻进行监控及保护。
Type-C接口温度监控:
监控充电接口的温度,尤其是充电的时候,易产生高温。当接口温度升高时,NTC热敏电阻的阻值随之下降,电路中的电流也会相应变化。通过检测电路的电流变化,可以实现对充电器输出功率的调整,或是触发温度报警暂停充电,从而控制接口的温度避免过热。
CPU温度监控:
当手机长时间高性能处理,CPU会产生大量热量,热敏检测过热做出反应对手机进行降频,避免CPU过热损坏。
功率放大器温度补偿:
NTC热敏电阻在功率放大器的作用不仅是温度监控和保护,还包括温度补偿,以提高功率放大器的线性度和稳定性,避免放大失真。具体来说,将NTC热敏电阻的输出电压信号经过功放器放大,并与功放器的控制信号相结合,通过反馈控制来实现功放器的自适应温度补偿。这样,温度升高时补偿电路会自动降低功放器的增益或调整偏置电流,从而保持功放器的线性度和稳定性,避免放大失真。
顺络片式NTC热敏电阻应用案例举例(TWS)
TWS电池仓温度监控:
TWS电池仓也常使用锂电池,因为电池保护板上也有一颗热敏用量监控电池温度。
TWS左右耳机温度监控:
耳机内部空间较小且含锂电池,需要对散热以及电池温度进行监控,防止高温烫伤人。

※□:电阻的公差代码,精度最高可达±1%
※◎:B值的公差代码,精度最高可达±1%
NTC热敏电阻选型原则
根据线路对温度感知要求,确定R25及B值,即片式NTC的R-T曲线,要 求此曲线与线路温度感知敏感性拟合,使得同一温度变化下,阻值相差很小;
若需提高线路温度敏感性要求时,则须选择B值高的片式NTC元件,B值越高,相同温度变化时阻值变化越大,体现在电压上变化越大,可识别的电压点越多;
若需降低线路温度敏感性要求时,可用极低温度系数的线性电阻与片式NTC串联,来降低其R-T曲线的B值(使得同一温度上升时,测试NTC的分压和NTC加电阻的分压相比更小)。

热电偶、热电阻及NTC热敏电阻的性能对比
温度传感器是指能感受温度并转换成可用输出信号的传感器,感温元件是温度测量的核心部分。温度传感器按感温元件特性分为热电偶、热电阻和热敏电阻三类。顺络电子温度传感器采用的感温元件为NTC热敏电阻,通过测量NTC热敏电阻的电阻值来确定相应的温度,从而达到检测和控制温度的目的。
