【经验】新电元车规级MOS P140LF4QNK击穿原因以及设计注意事项
某客户设计一款车载EPS,使用预驱的方案设计H桥驱动电路,但是在实际测试中中发现,经常会出现MOS管烧掉的现象,之前怀疑是驱动芯片有问题,在更换驱动芯片之后问题依然存在,本文主要帮助客户分析MOS管击穿原因,以及设计需要注意事项。
我们一般认为MOSFET是电压驱动的,不需要驱动电流。然而,在MOS的G、S两级之间有结电容存在,这个电容会让驱动MOS变的不那么简单。
比较好的方法就是应用专业的MOS驱动芯片,在本例中客户应用一颗微芯的大电流MOS驱动TC4420,车规级MOS选用新电元(SHINDENGEN)的P140LF4QNK。
实测MOS GS波形如下:
在不超一分钟时间MOS直接击穿烧毁。一般来说出现这种原因就是驱动布线太长,寄生电感太大引起的。
虽然有栅极电阻,但是依然MOS会烧毁。同时阻抗也不匹配,出现这种情况客户只能重新画板设计。在我们设计MOS驱动电路时一定要注意布线同时也要匹配好阻值。
因为驱动线路走线会有寄生电感,而寄生电感和MOS管的结电容会组成一个LC振荡电路,如果直接把驱动芯片的输出端接到MOS管栅极的话,在PWM波的上升下降沿会产生很大的震荡,导致MOS管急剧发热甚至爆炸。

【经验】一文解析MOS管的源极和漏极的区别
源极简称场效应管,T仅是由多数载流子参与导电,与双极型相反,也称为单极型晶体管。漏极利用外部电路的驱动能力,减少IC内部的驱动,或驱动比芯片电源电压高的负载。本文SLKOR将介绍MOS管的源极和漏极的区别。
