Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
From the datasheet and AN4870, we understand that it is necessary to calculate the battery's internal impedance and measure the OCV table.After configuring CC_CNF and REG_VM_CNF, the STC3117 operates properly using its algorithm.The operating tempera...
Hello!I have a L9963E in 192 cell EV battery setup, there's 16 modules daisy chained, each handling one 12S pack. The bottom module has a L9963T and stm32 chip that handles the whole pack and communicates with car through CAN bus. Everything is worki...
Hi everyone,for this driver I am seeing 700 ns sw deadtime also deadtime: 800. What is difference between them and which one is in use in application. Second question why it is 700 or 800 ns because according to Mosfet datasheet this values is too lo...
Hi,We are currently testing the above chips.I have a few questions:Can I get information or documents stating how to download firmware using an external MCU and the reference design for that? We use 3.3V I2C communication, and I understand the ST chi...
Dear All,I'm using the evaluation board STEVAL-IFP033V1 Galvanically-isolated 8 channel high-side driver based on the ISO8200BQ.I powered the board with 22.8VDC, all outputs on from the isolated side (all LEDS green on the output connector)I checked ...
Posted on November 05, 2016 at 19:04 Hi I would like to use L7987LTR in a few designs. The datasheet of the IC says its able to provide 2 A current however I can only measure 0.5 A. I have tested the schematics in 3 different layouts and l...
I was recently testing the FOD reping behavior and noticed that when FOD is detected and FOD reping is enabled, the TX retry delay is fairly short (a few seconds).Are there any settings to increase this time delay?If a foreign object keeps getting de...
I am using SPI to control L6482 and then control the stepper motor, but I don't know the complete control process. Can you provide me with a reference configuration? 我在使用SPI控制L6482进而控制步进电机，但我不知道完整的控制流程该是怎样的，你们能否给我一份相关的参考配置？
Can you help to explain the function of these GPIO settings on the RX IC?0x0A - RX power Out OD - this function is not mentioned in the datasheet or EVK user guide but is available through the GUI. How does it work?0x05 - what does FW ready indicate?...
We are looking into wireless chips from ST, but all pages related to wireless charging seem to be gone!For instance, the chip can be found on the store still:https://estore.st.com/en/products/power-management/wireless-charger-ics.htmlBut the datashee...
