Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
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...
Help to make this circuit Three phase sequence detection with Transformer less power supply three phasemicrocontroller based where we can detect under over voltage also. please help to make this and suggest solution?
Hi all,I am using the STUSB4500 to power a device with a large inrush current. I have configured the PDO's for 20V @5A which should be more than sufficient to meet the power requirements. I have selected POWER_ONLY_ABOVE_5V so that it will not attem...
Hello,We completed a test of bi-driectional communication of the Proprietary Packet feature (PP) for a mass market client using the STWLC38 (RX) and STWBC86 (TX).We're able to consistently receive the data of 5 bytes reliability from the RX to the TX...
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....
