【技术】瞬态抑制二极管在BMS上的三种应用场景介绍
BMS一般分为主控模块和二极模块,主控模块主要是负责电池电压、温度、电流等监测数据的采集以及均衡控制,二极模块主要负责SOC估算、继电器驱动以及电气损坏保护。TVS(瞬态抑制二极管)在BMS上的应用主要有哪些?你知道?下面优恩半导体就来介绍一下吧。
瞬态抑制二极管在BMS上的应用场景有三大块:
一、KL30电源端口处放置一个TVS瞬态抑制二极管起保护作用;可两个TVS管串联或并联使用。如下图,TVS管放于电源入口端,负载放于其后端。
二、采集板AFE的电源端口处放置一个TVS管做防护,同时串联压敏电阻一起使用,这个是比较常见的一种防护设计方案。
三、对于BMS控制板上的信号端口防护,例如IO信号以及通信信号,这些信号都要考虑ESD防护问题;所以此时一般选用专用的ESD防护TVS管。
TVS瞬态抑制二极管在很多应用场景中都会用到,方案也有很多种,需根据自身需求而定。

【技术】浅析瞬态抑制二极管(双向TVS管)
TVS管也叫瞬态抑制二极管,TVS管是吸收浪涌功率用的,能在极短时间内承受反向电压冲击,使两极间的电压钳位于一个特定电压上,避免后面的电路受到冲击。简单的说就是做过压保护的,在通信等产品中很常见。连接时必须反向工作在电路电源、地两端,与稳压二极管类似,但不需要限流电阻。
