STEVAL-ISB68WA does not work with a commercially available 5W Qi compatible transmitter. Is this normal?

Hi,I am working on a wireless power receiver test board 2,5W STEVAL-ISB68WA to develop an application with wireless charging.STEVAL-ISB68WA does not detect a commercially available 5W Qi compatible transmitter (this one works properly). According to ...

Can I use STUSB4710 without using ST1S14? I am already using another DC-DC converter to provide voltage, but there is no feedback pin for the same. So, is it compulsory that I should use ST1S14?

STSPIN32G4

Hello ,We want to drive two independent hub motor ( as like hoverboard) with STSPIN32G4 . Product overview says "Finally, with an additional external three-phase driver (such as the STDRIVE101) two independent 3-phase BLDC motors can be efficiently d...

If I dont use schottky or TVS diode between output of the IC and ground, do I damege the IC because of back emf voltage ? (VND5E160AJTR-E)

Hi all,I am using VND5E160AJTR-E for driving a inductive load. The values of inductive and resistive load is 15 mH and 12 ohm. As you know happening back emf pulse while driving a inductor load and I dont use schottky diode for cutting off back emf b...
