Part Number: UC2625 Other Parts Discussed in Thread: UC1625-SP Hello,
Whenever I try to run a motor (I'm using a maxon 272763) with no load, the system triggers constant current mode on my power supply constantly while the motor is spinning (I have it…
Part Number: UC2625 Hello,
Do you have information on the case to junction and/or the board to junction thermal resistance for UC2625MDWREP? Also what is the junction temperature rating?
Thank you,
Nico
Part Number: UC2625 An old design is using UC2625 in a peculiar way: the pwm is generated externally and the RC-OSC is synchronised to it using a transistor and some passive components.
The problem is that the motor is running very unstable at medium…
Part Number: UC2625
Hello,
I am currently a student with a limited background in electronics working on a small side project. I would like someone to verify a couple of connections on this schematic.
I am trying to implement closed-loop speed control…
Part Number: UC2625-EP Reviewing a legacy product with UC2625-EP.
New to motor control and currently have no hardware to verify the following which is why I am requesting verification of the interpretation of Data Sheet and U-115 app note.
BLDC Motor…
Part Number: UC2625-EP I am utilizing the UC2625-EP device that is rated to operate down to -55C. This only happens at extremely low temperatures between -45 to -55C. I am experiencing issues with the 5V, V Ref Signal, taking a dip in voltage from 5V…

Part Number: UC2625
Hello,
I'm looking to implement average current sensing with the UC2625 because using the pulse-by-pulse sensing seems to be limiting the needed in-rush current to my motor.
I see that Figure 8 in the datasheet states Figure…
