Part Number: UC2625-EP Tool/software:
Hello,
We are using UC2625MDWREP as a commutation chip which generates gate pulses for High side and low side outputs for controlling three phase BLDC Motor. With UC2625MDWREP , max 20V motor can be directly connected…
Hi Anthony,
Thanks for the response.
The RT and CT values were modified in the working board to 80.6k ohms and 10nF. The RPM decreased in a similar trend to that of non working board & will not work for our application and details as follows:-
Required…
Part Number: UC2625-EP Other Parts Discussed in Thread: UC2625 , The circuit follows Voltage control mode of UC2625. The RPM of the motor keeps increasing over a period of time from the desired RPM. lets say intented RPM is 4900 but after a duration of…
Part Number: UC2625-EP Hi
The circuit follows Voltage control mode of UC2625-EP. How to control the acceleration rate of the motor in Voltage control mode.
For our end application, the torque or acceleration of the motor has to be reduced for the same…
Hi Jan,
I apologize as I had a misunderstanding, UC2625- EP is an enhanced product, not a space product (SP) or space-enhanced product (SEP). We only provide radiation data for SEP and SP products. This product does not have available preliminary data for…
