Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hi,Since we haven’t received the datasheet yet, we’d like to confirm the following information:If the receiver side (RX) uses the STWLC89 15 W solution, what is the corresponding 15 W transmitter (TX) model?Which Qi standards are supported by STWLC89...
Hello I tried to design a 3-output AC-DC converter using the eDesignSuite. But the software only provides the turns ratio for the transformer and no core suggestions or what so ever was shown.I don't get the idea behind the eDesignSuite software that...
I need to use in our application three phase power supply any of the two phase present power supply should work or with respect neutral also work if any of one phase present. required for voltage monitoring three phase or sequence detector. any refe...
Problem SummaryWe have developed a three‑phase servo motor drive using STGAP2SICS isolated gate drivers and IPW65R190C7XKSA1 MOSFETs.The inverter works perfectly at low DC input voltage (25–40 V DC).However, when we apply 230 V AC (rectified ~320 V D...
Hi,I'm designing a custom PCB and I'll be using a VNQ9080AJ to drive 4 inductive loads (hydraulic valve spools).Is the protection diode in the datasheet sufficient for that application?The device will drive up to 28 VDC ~3.5 to 5 amps inductive loads...
I'm trying to use GUI(STSW-L9963E=L9963_evaluation_GUI.exe) for EVAL-L9963E-MCU.I installed all the S/W which is listed in maunal for operating GUI.And I have set all things needed, I think.If I connect the board and start a GUI, COM port turns on gr...
Dear STMicroelectronics Support Team, We are currently using the STEF12S eFuse in a 12 V power distribution design and would like clarification on the correct usage of the EN/FAULT shared pin, specifically from a microcontroller software perspective....
When configuring the system, firmware version 1.6 is detected correctly. However, when the configuration ID is set to 1 as mentioned in the manual, it is not acknowledged by the device (shown in red).
Hi, I'm checking the flammability specifications for MJD31CT4. I need to know if the molding material of this part is rated UL94 V-0. If it's not V-0, could you tell me what the official rating is? Any link to a supporting document would be much appr...
Hello everybody,I'm using an L6981C50DR for supplying a small board with 5V. The schematics is attached and should be perfectly conform to what is described in the specification from https://www.st.com/resource/en/datasheet/l6981.pdf as "Figure 4. Ba...
