DRV632EVM: DRV632 UVP引脚的作用

Part Number: DRV632EVM
Other Parts Discussed in Thread: DRV632, DRV603

请问一下DRV632PWR芯片的UVP引脚, 这个防止芯片POP声的,附图是DEMO板的应用电路图,测试UVP引脚的,当在硬件模式没MCU的情况下UVP引脚能不能悬空不接任何的器件?或者这样接对不对的?

另外请问一下DRV632PWR的工作频率,如DEMO的PVDD,PVSS引脚都是通过1UF的电容到地,CN.CP引脚也是连接一个1UF的电容,请问这样的工作频率多少KHZ?如果想调节这个工作频率,是不是只要调解CN.CP引脚的电容量就可以?
