I need some clarifications regarding the IC from STMicroelectronics: VN9E30FTR – 6-channel high-side driver with 24-bit SPI interface for traffic signal controller applications. In the datasheet, it is mentioned that the internally limited current i...
Could someone tell me what type of diode I have? I can't find any data.L X GP128I appreciate your help.
Hi,I have a question about the RUN command because there are different speed to MOVE command.In RUN command the speed min its 0,015 Step/second , in MOVE command the max speed min it is 15.25 Step/Second.I need run the motor at very low speed similar...
Now I start to use STPS202000CFP and try to estimate junction temperature. Then in datasheet, ST defines Rth(j-c). Question1 : where is "c(case?)" point in this discrete device, center of case?. Question 2: Does Onsemi have Rth(j-a) for this device ?
Hi,I am using HVLED007 in my 80V, 45W SMPS (Input voltage range 160V-300V). Is it possible for the IC to operate in primary side regulation mode instead of the conventional opto-coupler-based secondary side control? Unlike other ICs, I cannot see an ...
I plan to use the LD1086DT33TR LDO to output 3.3V with an input voltage of 5V. However, I am not aware of the requirements for the ESR (Equivalent Series Resistance) of the output filter capacitor for the LD1086DT33TR, and this parameter is not menti...
Hi, I'm working with this VNQ7E100AJTR IC , I have a connected the solenoid of rating 2.2A rating at one output channel. the particular output pin got damaged and irrespective of the input the particular output pin is always High (12V). what is the m...
We have a prototype board with the STSPIN958 full bridge but we see that it cannot measure positive current (in coil) when the voltage is switched negative, output shows current = 0.We switch from 48V to -48V on the coil. (turning the magnetic field ...
Hi,does anyone in the world have used a STSPIN948 with a stepper motor?I'm having many problems, also because of lack of documentation and examples.I need to control a NEMA 23 motor, but if it turns slowly it works, over 2 turn per second it hangs.I ...
Hi,I was hoping someone may be able to point me in the right direction for two projects I am looking to research:1.) BMS - to what extent is there a mature ecosystem and codebase for scalable battery management - not only for varying call capacities,...
