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】解决MG048A功率模块中MOSFET驱动震荡的小技巧

一般认为MOSFET是电压驱动的，不需要驱动电流。然而，在MOS管的G、S两极之间有结电容以及在PCB布线中寄生电感的存在，这个电容和电感会让驱动电路在驱动MOS管变的不那么简单，很容易造成驱动波形异常，特别是驱动波形震荡。本文将结合在电机驱动应用中的Shindengen（新电元）的MG048A功率模块，谈谈如何解决MOSFET驱动震荡问题。

MOS管输出特性曲线，你看明白了吗？

我们知道，三极管是利用IB的电流去控制电流IC的，所以说三极管是电流控制电流的器件。而MOS管是利用VGS的电压去控制电流Id的，所以说MOS管是电压控制电流的器件。对于N沟道增强型的MOS管，当VGS＞VGS(th)时，MOS就会开始导通，如果在D极和S极之间加上一定的电压,就会有电流Id产生。

【选型】如何为智能光伏接线盒选择用于开关的MOS管？

在智能光伏接线盒中，当光伏面板正常发电时，MOS管处于关断状态；当光伏面板异常时，MOS管要立即导通，将异常光伏面板“旁路”掉。因此，在智能光伏接线盒中，MOS管对整个系统高效、安全运行，起到重要作用。Shindengen（新电元）是世界知名的功率器件半导体方案供应商，其推出的N沟通MOS管P13LA10EL，具有开启电压小、开关速度快、导通电阻小、体积小等特色，恰好满足智能接线盒的需求。
