Resolved! STWBC86 and STWLC38 Adaptive Charging Circuit
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...
ISO8200BQ RDS(on)
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 ...
L7987LTR only provides 0.5 A max current rather than 2 A.
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...
Resolved! STWBC86 FOD Reping behavior
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...
Issues with VNQ9080AJTR Quad-Channel high-side driver Output and Input Behavior.
Hello STM Community, I'm currently working with the VNQ9080AJTR Quad Channel High-Side Driver, and I'm encountering a couple of issues that I hope someone here can help me resolve 1.Output Voltage Regulation: With a constant VCC supply of 12V, the ou...
SPI control requirements for L6482—L6482的SPI控制需求
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？
STWLC38 GPIO Functions
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?...
Why are all the wireless charging related pages redirecting to "404 Not Found" pages?
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...
Resolved! About stwlc38 firmware update
Hi, Due to my mistake, when using the GUI tool to update the firmware, I mistakenly loaded the configuration file into both the PATCH and CONFIG sections. As a result, the chip is not functioning properly and cannot connect to the GUI tool. Is ther...
Thyristor Short in field deployment
Hi Team, We have used a Thyristor for our 24v input protection and conducted lab tests for 24v inputs by feeding upto 2kv surge. When the device is tested with normal regulated power supply or SMPS. The device is ok but when it is deployed in field t...
