Hello guys please I have a question.
Am making an inverter with SG3525 as the oscillation driver circuit. Now the issue I have is , when ever I turn on the inverter, one channel of the MOSFETs gets hot, while the remaining channel is cool and okay, and before I see the cjhannel with hot heat...
Hello,
I'm designing a circuit to ring a bell using a code set by the user. When powered the circuit steps through the code which is set via DIP switches to decide where a "ding" or a space should be within the code. Each "on" position within the code actuates a modified car relay which hits...
Can anybody advise me if the circuit attached will function as required.
The external timer supplies a 6 volt signal to the relay coil for between 3 & 9 seconds, this in turn drives the 12 volt motor for the 3 to 9 seconds & it also charges the 220uf capacitor.
At the end of the 3 to 9 seconds...
Question:
Design a 3-input NOR gate. If the PMOS devices are half as conductive as the NMOS devices determine the correct transistor sizes.
I understand how to design the pull up pull down circuit, just unsure about calculating the correct transistor sizes. Thanks
I have been looking into back-flow protection for batteries and chargers and invented this wonderful circuit, and as usual when you search you find that it has all been done before. Just so in this case and the circuit in Figure #5 of the application report linked below, not only uses a similar...
