Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
In STEVAL-KITXCB for controlling SD/OD pin of L6491 using such method. PWM_en connected to MCU pin. I want use same principle in my design. Can anybody describe how program this.Is such hw connection support both function for enable PWM and for contr...
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...
Hi, I am designing a 25W power supply for the raspberry pi 5 for my battery powered project. The buck regulator I am using has a fixed 5V output and I want to use the STUSB4710 to offer 5V 5A to the Pi. How can I program the registers to do so via I2...
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...
Dear ST Technical Support,I would like to inquire about the short-circuit protection behavior of the VN7003ALH high-side switch.Application: Board with 6× VN7003ALH outputs.Configuration: 24V supply from 200Ah lead-acid battery. Output wiring: 1.5m o...
Hello. Could someone please recommend a good power board that can power and control two gimbal 3-phase BLDC 12V motors with encoders AS5048A https://www.sparkfun.com/gimbal-motor-with-encoder-12v-587rpm.html ? I use the STM32 NUCLEO-64 F401RE microco...
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...
Hello Team,I am using the STUSB4500 USB Power Delivery controller in my design.I have designed my board by strictly following the reference schematic provided in the STUSB4500 datasheet. However, the board is not working as expected.I have already tr...
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...
