I would like to know the working principle of the charger bump for MH98, as well as the working principles of CPOUT, CP1, and CP2. Why can the voltage of the bootstrap capacitor reach 11.3V when VDH = 6V? In other words, why can the voltage of CP rea...
Hi all. The data sheet for the LDL212PUR low dropout linear regulator does nor specify the quality of the input and output bypass capacitors with regard to ESR or loss tangent requirements. Most LDO regulators require at least one low ESR bypass cap...
I am writing because I have a question about the L9369 chip. The second case of above table ( SPI_GIOx_HSCtrl == 0 and SPI_Off_Giox == 1) , Output is set to HIGH. I'm curious why GIOx Output is HIGH when SPI_GIOx_HSCtrl is 0. Thank you.
Hi~ I am curious about the solution which referred to the wBMS I heard that you have BMS solution SOC. But I haven't heard about the wBMS. If you have, please let me know it Many thanks BRs Daniel Lim
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 ...
