Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hello allI don't know if this is the right sub-forum, I chose the one that seemed the closest.I've been spending a bunch of time trying to find the part number of a seemingly simple IC, but just hitting walls. I've Googled using the manufacturers nam...
Hi all, I am looking for two voltage references to produce two rails ( positive and negative) with low frequency noise.The voltage reference does not need to have a tight output voltage accuracy and long term precision. It needs to be stable over a 1...
I'm reviewing the datasheet for the LM317 linear regulator, and it lists the equation for calculating voltage as:VO = VREF (1 + R2/R1) + IADJ R2If I plug in the numbers from my circuit (and neglect the error calculation), I get:1.25 * (1+(1400/400)) ...
I have followed the design attached in PDF. It is from ST designsuit.I have used MYRRA 75032 flyback transformer. (Datasheet Attached)Optocoupler 140105146000 with CTRmin - 50%, CTRmax - 150%.So now problem is I am not able to get continuous Vout fro...
Hi everyone, I’m using the STGIB8CH60TS-E IPM in my motor drive design and trying to configure the smart shutdown (overcurrent protection) function using the CIN pin. As per the datasheet, the internal comparator reference voltage (Vref) is typically...
Which alarm to read if our motor skips steps while moving? The motor works fine for a period of time like for 4hours and then randomly starts to skip step while moving in forward direction whereas in backward direction it moves fine. We are using 1/4...
Hello Team, We are using VN9E30F High Side Driver, when we try to communicate it through SPI, the SPI Error Bit of Global Status Byte is getting Set and Reset as well. We are Following Below Configuration for SPI:- Could anyone help me to verif...
Hi, I wanted to ask the group if the demo code "SPC58EC - AEK_POW_BMSLV application for discovery" already includes automatic cell balancing, or if it doesn't, or if it needs to be enabled somehow. I was also interested in knowing if there was a GUI ...
Hello STMicroelectronics Support Team, I would like to make a custom wireless power transfer based project. I was trying to download the GUI (STSW-WBC2STUDIO). I am planning to use STEVAL-WLC38RX and the STEVAL-WBC2TX50. Please send me the softwar...
I have a powerSTEP01 driving a stepper motor with the coil current set to 2A. However, the current flowing in the coils is unstable when it is flowing in one direction:Sorry about the image quality - I have an old 'scope, so had to use a photo ;)The ...
