L6480H stall detection does not work. What should I do?
Hi everyone!I want to use the ST EVAL6480H board to control a stepper motor but I get stuck with the stall detection feature of the chip. My problem is that it always generates stall (step loss). I have tried it with different configurations and wit...
Multiple L6470PD via daisy chain.
Hello FolksThe L6470 datasheet (see snapshots provided by Jacek) clearly says that Vreg should be connected to VDD, as they are not connected internally. Further, VDD should have 10uF Cap to work properly.Surprisingly, the X-NUCLEO-IHM02A1, which has...
i am using L6566BH for high voltage SMPS. Its not turning ON with load. if its not connected with load then its working. Can you please check and revert with the solution.
Input is 300 to 800V DC and output is 24V DC. Attached the schematics of the same.
When STC3115 power gauge depicts an incorrect SoC value (remaining charge in battery), showing a value less than the correct one, may STC3115 discharge calculus be artificially forced to a lower discharge rate by changing the declared value of Rsense?
Although for 3 different batteries we managed to get the expected SoC and duration of battery discharge, we are facing difficulties in getting the expected discharge time for a fourth battery type. We followed the same procedure used to characterize ...
Noise on the powerstep01 Busy line
We need to use the Busy line as an interrupt and have noticed that often there is considerable switching noise on that line, making use for that function unreliable. We currently pull it up to VREG with a 39K. We have tried reducing this resistor to...
temperature affect L6470 Stall detection
I am using stall detection when stepper motor enter under force. but temperature affact detection system. I am using same force in same system but stall detection feedback is different position in different temperature. I need to find force position...
Is IGBT reacts like MOSFET?
I have designed a ballast to reduce DC voltage before the power supply driver (UCC28880).This ballast was first do with MOSFET 1200V : it was OK. We decided to replace the MOFset by IGBT (STGD5NB120), and then the ballast generates noise ( like crak...
Resolved! STSPIN32F0 external 3.3V power supply issue
mode 1：SW pin short to GND or VDD，how to short ？connect direct or use resistance（what is the best value？）， internal swith will not workmode 2 ：SW pin NC or connect to VM，but the internal swith is working still。in high temperature ，High efficiency ，L...
ST1S03: Can efficiency be improved?
I am using ST1S03 in the inverting configuration shown in Design Note DN0011. Input 3.3 V +/- 7%. Output -3.3 V ~150 mA.I am getting efficiency only ~69-72%. Which, now that I look into it, is not much worse than the datasheet typical value of 70-75%...
Viper Flyback Converter design ?
Dear Members,where can I download updated version of :Viper Flyback Converter design software ?I checked the bom, but can not find the value of F1, Th1, C1 and L1, thanksScreen shot :
