Other Parts Discussed in Thread: CSD87333Q3D, PMP9128, UCC27211
我想使用TPS51604配合CSD87333Q3D组成三相全桥用于电机驱动。具体情况是：
1 电源电压12~24V；
2 使用7805产生TPS51604栅极驱动需要的5V电压；
3 用MCU的PWM驱动，同时MCU的GPIO端口用两个22k电阻分压后连接nSKIP，GPIO置低时使能驱动，GPIO拉高时nSKIP经电阻分压得到1.6V左右的Tri-State电平，以禁用驱动；
4 栅极驱动电阻22Ω，无栅极滤波电容。
以上的用法是否有问题？
另外还有一个问题，母线24V以下使用时，TPS51604驱动CSD87333Q3D的栅极有没有必要设计米勒钳位电路？
I would like to to design a three-phase full bridge for motor drive with TPS51604 and CSD87333Q3D, Here is the detail:
1. Power supply DC 12 to 24V;
2. 5V of TPS51604 gate drive is generated by 7805 ;
3. TPS51604 controlled by a three channel MCU PWM port, nSKIP is connected to a two-22k resistors devided MCU-GPIO port. Pull GPIO down To Enable TPS51604, Pull GPIO up, as nSKIP get a Tri State level of about 1.6V to Disable TPS51604;
4. 22 Ω Gate drive resistor , no gate filter capacitor.
Is there a problem in the plan above?
Another question :
is it necessary to design a miller clamp drive circuit for the CSD87333Q3D gate driving with TPS51604 with 24V DC-bus?
