Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
We require to set parameters like Duty cycle, Bridge voltage, Frequency, etc. for WL Transmitter operation.We are using STEVAL-ISB027V1 power transmitter evaluation board with STWBC GUI, but we are unable to set mentioned parameters using parameter w...
I'm doing some research on stepper drivers an the L6219DS fits the exact needs. In order to do a proper evaluation i need to overview the lifecycle data. Can anyone provide this information for me. Would be a shame if this driver becomes obsolete ver...
While finishing my porting of the B-G431B-ESC1 board for Arduino using STM32duino (which worked great - thanks STM team) I had to dive quite deep into the schematics. One thing that is unclear to me is if the L6387 MOSFET driver chips should be reall...
Hi All!I also used eDesignSuite to build two 3.3 and 15 volt power supplies. This is what the program generated for me:I made two boards according to these diagrams:In the process of testing them, I found that in the absence of a load, the voltage at...
I purchased "STEVAL-LLL009v1" for the design of "LLC Resonant Conventor".I can download the HEX file from the following link, but I can't find the firmware source.Please help me.https://www.st.com/content/st_com/en/products/embedded-software/evaluati...
Hello,1- can we use a higher current motor with the Dev -board since the Mosfets STD140N6F7 have Id 80A?2- in the schematic of the steval_spin3201 the VBUS and the VM are connected with JP2.My question is: if we supply VBUS with 48V and open JP2 can ...
I am looking at the ST’s N-channel part VN920B5. But I notice there is VN920B5-E, VN920B5TR-E and VN920B5HTR-E. I look into the datasheet, it only shows VN920B5-E is tube, and VN920B5TR-E is tape&reel. There is no indication of what ‘H’ means for the...
Hello everybody, I have a question I can't solve. I use the X-NUCLEO-IHM03A1. My question is : wath is the link between the TVAL values in the register of the Powerstep01 (see figure) and the voltage accross the shunt resistor of the board (100 m ohm...
Hi, I am using the PM8805. I need Class 3 and 4 and so I used datasheet's table 7 (classification table) which says, that one resistor 36R5 is needed on CLS1 pin and a open connection is needed on CLS2 pin. There should be the result 0 on T0 output f...
I bought the STEVAL-ISA147V3.The software was not included.The company I work for is Lutronic.I am a medical device developer.It will be used for product development.I would appreciate it if you could send me the firmware.*Moderation Edit: please do ...
