H桥的输出电压不正确

我和H-Bridge'VNH5180A'进行了交互。我试图找到问题好几天了，但我找不到它。

H桥的输出电压不正确。

在桥的Pins是这些电压。我用示波器测量它们：

感谢您的帮助。

I having traouble with the H-Bridge 'VNH5180A'. I tried to find the problem now for some days, but I wasn't able to find it.

The H-Bridge haven't the right output voltage.

At the Pins of the Bridge are these voltages. I measured them with an oscilloscope:

Attached is a picture of my layout, of the datasheet from the H-Bridge and an Osziloscop picture of the H-Bridge output Out_A -Out_B.

Thanks for your help in advance.
