The schematic diagram is as follows.Use only STEP/DIR standalone mode.Two-layer PCB,Now after power on, OB1/2,OA1/2 voltage is equal to the power supply voltage VS; When EN is enabled, the chip will burn. What is the reason

现在解决了,是VS引脚烧掉,应该是VS引脚加的电容太小。还有个小问题是,先VIO通3.3V,再给VS上电瞬间,DIAG所接的指示灯会闪亮一下,断电时也是,断开VS24V,也会亮
diag 有几种可能性。 您可以参考一下规格书的图15.1 看一看是不是哪里触发了。
这个可能具体需要排查一下。 您可以按照下面图的逐条进行排查。
