【技术】金瑞电子JKPPTC系列超低电阻PTC的主要功能介绍
锂离子电池快保护线路板示意图
其电路主要组成部分:
贴片电阻、贴片电容、场效应管(MOS)、控制IC。有的有PTC、NTC、识别电阻(IR)等。
其中PTC的主要功能:
*过流保护器(PTC):
正温度系数热敏电阻(PTC),起到过流高温保护作用,同时又是保护线路板失效后的二重保护。如果没有PTC保护,同时电压保护电路失效,电池就会在过充或滥充时产生过多热量,引起内部损坏。这都会使电池破裂、漏液、冒烟甚至燃烧。
PTC保护器件是和电池组里面的原电池串联在一起电路的主回路上方,无论温升是由于外面出现短路造成还是由于过度充电引起,它都可以起保护作用,不再需要热熔断丝或者双金属断路器。
JKPPTC系列超低电阻PTC,有效解决因加PTC元器件而增加手机电池内阻带来的电池的有效使用率降低的问题,各种SMD封装和大电流产品满足各类电池的要求。
