Hello,

 

Is it possible to control 2 BLDC (each with 2 shunts) with FOC with KV4x?

I saw that KV5x will. But with KV4x?

I need acctually PWM for 3 phase predriver for 2 BLDC. So the signals input for 6 Mosfets pre-driver for the first motor and 6 Mosfets pre-driver for the second.

I also need to sample current on two shunts on each motor. I wonder if with only 2 ADC from the KV4x series it is possible to sample on one motor and then the other dynamically.

Is it possible to trigger them in center aligned PWM on each motor?

 

Is the KV5x arriving soon?

 

Sincerly,
