Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
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 ...
Hi! We have designed a custom board using STWLC38 but its not working. We also have the Evaluation kit of STWLC38 and Im using the same coil to test my custom board. Im getting roughly 0.6V at VRECT pins after nearly every second. I aslo have attach...
Hi,I am working with a battery pack and the BMS. I have connected everything correctly to the board and after a first run everything seemed to work properly, the board was receiving commands from the MCU through the translator ISOSPI, and the green l...
