Hello everyone. I would be very grateful if you can help me with this circuit I am working on (sch.png).
It consists of a TP4056 charger/controller (Photo 2) connected to a 3.7v/3Ah Lithium Ion battery to supply a low battery level indicator, and a load (three white leds and two fans) through a...
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...
