Should I bother including this current limited high-side power switch component (ST890) on my custom board. I want to know if this component is as critical on a board that is expected to be powered either by USB or an external battery. From what I’ve read, it enables/disables power delivery based on the ON pin and is capable of switching off automatically when exceeding a certain temperature.

Hi, I am testing a 600W LLC half bridge converter and had a problem with oscillations on my output diodes. By removing the output filtering inductor the oscillations went away completly. I tried searching about the effect of an output inductor but could not find anything about that. Any help would be appreciated. Thanks in advance.

I am building a 1936 Chevrolet pickup and it has a 261ci straight six with 3x2 Stromberg carburetors and I am installing an inline fuel pump and my dilemma is that the pump just keeps pumping when I have just the key on and so therefore it just keeps filling the bowls and intern just keeps dumping fuel into the engine which is obviously not safe for one but not good for the engine, so I'm trying to figure out a way to design or if it already has been done, a auto shutoff switch which works...

Hello crew,Withing the more general scope of making electronic music, I am trying to build this oscillator based on a 4049 chip:I know it's crap, but it's simple, which is good for learning I have breadboarded it successfully, I'm using a 12V supply and playing with the RC values I can adjust the frequency. Yay!Now I am trying to add voltage control to the thing. I have found another schematic with an added 1M resistor at pin 3 that says to connect CV there.

From what I can find on the web, this flag should get set to 1 after the device has physically transmitted it's payload. But it isn't, I poll the FIFO_STATUS register but the flag never gets set and I know the data was sent because I have a receiver board that receives the whole packet. The manual for the device too, has very little to say about TX_EMPTY, this is the only place the field is mentioned:The flag is set right before I begin a payload transmission.
