近期在阅读电机驱动DRV8305手册时,有点疑问:
The internal handshaking uses the VGS monitors of the DRV8305 to determine when one MOSFET has been disabled and the other can be enabled. This allows the
gate driver to insert an optimized dead time into the system without the risk of cross conduction.
手册中描述驱动内部有握手机制,通过VGS MONITOR,确保上下桥两个管子中只有一个disable了,另外一个才能enable,既然已经硬件实现了,那时不是意味着不需要再额外添加死区时间了,但手册中似乎也不是这个意思?
