STEVAL-BMS114TX no signs of life
Hello,I am looking for an IC to monitor cell voltages of a 12s lipo battery.I found the L99BM114 IC. To get started, I bought the STEVAL-BMS114TX.Currently, I have connected 12 resistors in series to my lab supply with 48v. In between these resistors...
Power Consumption of L9963E
Can anyone help me understand the basic power consumption of L9963E before and after wakeup?
Resolved! VBATMON Operating and Absolute Limits – L9678P
Dear ST Support Team, We are using the L9678P in an automotive design where the battery voltage is nominally 28 V. From the datasheet, we understand the following for the VBATMON pin: Absolute maximum voltage: 40 V Operative maximum voltage: 18 V We ...
EVAL-L9963E-MCU GUI
Hi, i made up a set up of 4 cells and I connected them to the connector of eval-l9963e-mcu. I already changed 4 cells, cause it seems like there is a dissipation for the cells. When I active the balance by GUI i don't see that the cells are balancing...
Connect eval-l9963e-mcu to Arduino UNO
Hi; i was trying to connect my eval-l9963e-mcu to an arduino uno, to comunicate by SPI. How can i do this?
STWBC86JR wireless charge efficiency
Hi,When we were using the STWBC86JR as the wireless charging TX, we encountered a problem. The design is defined as wirelessly charging the battery and supporting the product's operation. The tested charging efficiency was relatively low, only 43%. W...
STUSB4700 - with data
Our application requires charging a laptop at 65W via USBC with USB data passthrough to the laptop as well. A tablet computer is typically used to communicate with the laptop while it is charging. The roles would be aligned with the laptop acting a...
Need LED backlit LCD 200mA driver with PWM dimming
STM32F746G-disco board currently uses a STLD40D led driver. I am switching to an LCD that had 1000 nit output that can draw 150mA. Looking for a driver that can handle about 200mA with PWM dimming capability. Any suggestions appreciated.
STEVAL STWBC86TX programming
Hello, I would like to program a board with the initial configuration of the STEVAL STWBC86TX. To do this, I need two files: PATCH and CONFIG. Where can I download these files to the STSW-WPSTUDIO GUI of the test board we have?
USB PD and Data transmission from two DFP ports to one UFP
I want to design a USB4 Hub where one UFP USB C port has data connection and charging capabilities for a DFP, but can also get charge from a STUSB4710 that I'll supply with a DC voltage externally. So my hub would have a DC input and a USB C data I/O...
