Dears.
I found two BLDC motor controller Uc2625 and UCC2626.
But they have only a few data.
What's the defference between Uc2625 and UCC2626?
Just electrical characteristics? Or they have special function?
And I want to control the speed.
I found out UC2625 datasheet.
It said that Pin1(E/A IN(+)) can control the speed.
As shown Figure 14. 45-V/8-A Brushless DC Motor Drive Circuit, Pin 1 is connected with variable resistor.
Maybe the voltage level can change the speed.
Am I correct?
But I couldn't understand UCC2626 speed control sequence..Plz explain me about it.
Last..
I want to get reference design about these devices.
Can you support me?
Best regards
Harry.
