PowerStep01 application: Specify number of steps for RUN command ?
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...
Resolved! STCP202000CFP's Rth(j-c) definition
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 ?
HVLED007 in PSR
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 ...
Resolved! LD1086DT33TR and ESR
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...
Output current of each channel and pull up for open load detection (VNQ7E100AJ)
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...
STSPIN958 H-Bridge, current measurement in II and IV quadrant?
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 ...
STSPIN948 and stepper motor
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 ...
Question re: BMS control and Inverter control
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,...
Resolved! Stm32 Nucleo 767zi power on issue at 12V Vin.
Hi!I have an issue with stm32 Nucleo F767zi power setup.When I power up the stm32 Nucleo F767zi on 12V, the regulator ic and the controller chip heats up. Why?I have also changed the JP3 jumper to (Vin-5V) option. And the JP1 jumper is off.What's the...
