另外我想一个芯片的两个H桥可以并联驱动一个电机，那我想应该两个芯片4个H桥应该也可以啊，芯片资料上说 The two H-bridges in the DRV8833 can be connected in parallel for double the current of a single H-bridge. The internal dead time in the DRV8833 prevents any risk of cross-conduction (shoot-through) between the two bridges due to timing differences between the two bridges. The drawing below shows the connections.这里说了可以防止两个H桥之间交叉传导，那为什么到了4个H桥就不能防止这个功能了呢？是因为那个internal dead time 只能满足两个H桥的实现并联吗？
