Please show me a mppt IC
Hello!Our company is looking for an ultra-low power solar charging MPPT chip solution. Please recommend some suitable chip models, along with specifications, reference design diagrams, etc.1. The open-circuit voltage of the solar panel is 6V, and the...
STSW-2KW5CH48V - source code and related documentation
Hi,I am planning to design a 1.5 kW EV charger based on the STSW-2KW5CH48V reference design. However, I require the source code and related documentation to proceed with the development. Could you please provide the necessary source code and all rele...
Resolved! STWBC86 + STWLC38 - Overheating and low efficiency
Hello,We use the two products together for a Qi Transmitter (SWTBC86) and Qi Receiver (STWLC38) solution for a single product and it's accompanying charger board. The eval kits of both boards perform much better than our production design, particular...
Where is the Back-EMF on the STEVAL-ESC001V1 schematics ?
Hello,I am trying to develop my own sensorless motor control using the STEVAL-ESC001V1 Board. The motor used is a 6 poles BLDC motor. I have successfully been able to run the motor in open loop and it’s running well.In order to have feedback and esti...
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-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...

Can anyone help me understand the basic power consumption of L9963E before and after wakeup?
EVAL-L9963E-MCU GUI: balancing not working on 4-cell battery
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...
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...
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...
