HiI'm running a SMPM motor and i have resonace problem in mechanical system resonance frequencies: 1.2Hz 2.4HZ 4.8HZ and in other frequencies everything is ok. The resonance is low it noload but worse in full load.I ckecked current controller,angle,...
Hi Team, We are using the L9823 chipset and it is interfaced with imx9qm SOC over spi. Now, I gone through the code of linux kernel but I cann't see any linux kernel driver for L9823 ST chipset. can you please help us to get the linux kernel dr...
Hello Sir or Madam,We have designed an ESC according to STEVAL-ESC002V1 and used ST's 6Step_Library. In our application, There are commutation, noise and maximum speed problem. MCU and gate driver is STSPIN32F0AMOSFET is STL220N6F7Switching frequenc...
Hello,I compared the datasheet of L6562 and L6562A. Section 7.2 of L6562A mentioned that inv pin has dual functions and can be used as disable function. Is there the same function in L6562?If not, what way should L6599A use the switch to control L6...
Hello, I designed and manufactured a PFC circuit with a L4984D for 400V 800W output. I tested it until 860W with a resistive load and function ok. I need to power with it a 600W, 400V to 24V DCDC. This second step consist of a full bridge with a tran...
I am interested in developing a product using the STWBC2 wireless charging transmitter IC. Are there application notes, a reference design, or eval kit available for this component?
Hello,I am working with STC3115 and I would like to know, the maximum charging current that I can measure with it?
Hello!I use L7987L DC-DC as step-down regulator with input voltage range 9-60V. output 5V , 2A max.Online design offers schematic i use (see image).I have a trouble with dc-dc stability with IC.With some input voltage and loads It is instable. With l...
