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...
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...
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...
TwisterSIM is provided for free, but you need to get approval to use the full version.Is it illegal to continue using it as a trial version without approval?
At about 6.3A load the VN7050 switches off the output, which is much lower than I expected given the limit ratings in the datasheet, I suspect my thermal via's are not sufficient and that it is reaching an overtemperature condition, so have made chan...
Hi ! I'm using the VNHD7008AY, 24V powered, to drive a brushed DC motor, 3A. It works fine, but sometimes the VNHD7008AY burns. I think that the chip has a self protection, but it seams that it doesn't work or I'm doing something wrong. The problem h...
Please review and advise what is MSL(Moisture Sensitivity Level) of part#STP85N3LH5. We are aware that this part is "obsolete".Please provide a related link /document showing the MSL of this part.
Hi! I'm new in this forum, and my english is not the best, but I will try to explain myself. I'm charging Lead-Acid batteries with a transformer, and a bridge rectifier. If there was no battery, the signal will be a pulsating signal, but because the...
Dear support team, can I run both outputs of the VND5004ATR-E parallel to decrease the RDSon even more? So just connect both inputs and the load on both outputs? Thanks
Dear STM Team,Please answer to my below queries:1. Can you please let me know the maximum frequency can be provided to IPS1025HTR-32 and VN750PSTR-E to enable or drive high side switch?2. Can we drive these switches at lower duty cycle up to 1%? Rega...
