Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hello ST Team,We are observing that LEDs are minor glowing, during turn off condition due to leakage current. As per our application we are not not using any PWM configuration for LEDs. We are just making LEDs turn ON/OFF as per application requireme...
Hi, I am MURALI SELVAM from India, We are plan to build the circuit for Battery Monitoring circuit for which I select L9963E so someone give me suggestion for ensure L9963E part number is suitable for my project, My battery spec is "6S 25200 mA/h so ...
Hello everyone,I'm reaching out to the community because I'm encountering an issue with a Wireless Charger board we designed, based on STWBC86 and a similar architecture to the STEVAL-WBC86TX evaluation board.The main problem is the Power Transmitter...
From an ST newsletter I understood that ST is promoting new FERD diodes as "rectifiers for switching power supply". I could use these new diodes in a new flyback design so I downloaded a couple of datasheets and searched for Reverse Recovery Time Trr...
Hello,On my custom designed PCB, there is a USB port for battery charging and programming ESP32 microcontroller. When I plug in to the PC, I get "USB Not recognized" message. In addition, the two LEDs are light up. In the datasheet of the charger IC ...

I am using STEVAL-ISB017V1 (evaluation board of STC3117) with i.MX8MP board with linux. I am able to detect the IC and getting the data i.e. Voltage, temperature, current, and capacity. But the data for Current and capacity is not as expected. Curren...
I have assembled PFC and LLC circuit of STDES-3KWTLCP reference design. I followed the procedure as described in the document to assemble whole circuit. When we gave AC voltage to PFC, resistance R154 gets heat up and eventually burn out. I double ch...
Hi @Peter BENSCH can you help me how to modify the STEVAL-ISV020V1 to make the VEOC up to 5.3V?
Hello everyone,I have the STEVAL WBC86TX and RLC38RX evalboard here and I am currently testing them with the STSW-WPStudio.In my application I want to implement an custom inband communication between RX <--> TX. It seems that there is the possibility...
