Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hi, Im using the L9963E for a Battery Management System. I noticed that the device has a register called "FSMstatus". I don't understand if reports the current status or the previous status. For example, if the device is in SLEEP, in order to read t...
Hi everyone,I am designing a custom Power Distribution Board (PDB) handling up to 200A at 24V. This PDB will eventually interface with an STM32 and a Jetson Orin Nano for telemetry and control, but my current focus is solely on verifying the robustne...
I am testing the board with a 14s Li-ion battery, but I am unable to read the cell voltages or configure any register through the GUI. I shorted the X1 and P2 power supply inputs and supplied 12 V to both. This was the only setup in which I could g...
can someone help me with communication of l9961 chip to get voltages of 4s cells n current n charge accumulated by using esp32 or aurdino i dont have this chip n i am not a coder i tried my best but can get any data from the chip just i2c add 0x49 n ...
Hello, we are in the process of developing a BMS using an STM32 and L9961. We were wondering if there was any source or example code of a full BMS we could have access to in order to speed up our development. I am aware of the example code on the pro...
Dear ST Technical Support Team,I am currently using the ST1S10PHR buck converter in my custom PCB design to convert 12V input to 5V output.However, the regulator is not switching to the expected 5V output. The measured output voltage remains around 0...
I am currently considering the EVALSTGAP4S evaluation board for a laboratory prototype, and I would like to ask a few technical questions about its possible use in a motor-drive application.My goal is to build a 7-level cascaded H-bridge (CHB) multil...
Dear All, Could you please share us a technical document to show us what was the exat meaning of "N" letter of your part BAT54CNFILM-H/J ? Actually we ordered 6K pcs of your part BAT54CFILM from Digikey and its Digikey part number is 497-3786-2-ND bu...
HelloI am currently developing an AC switch for a heating boiler in a coffee machine.The boiler has a power rating of approx. 1200W. To control the boiler, I have opted for a triac circuit (T1250H-6I) with an optotriac (14230634300) and ZCC. I used ...
