    Rating of circuit breaker for protection.

    This circuit breaker is rated as 12V-48V 100A and I have to use this circuit breaker between additional alternator (24V 100A) in my vehicle and additional battery bank to provide overcurrent/short circuit protection. Will it be efficient to my 24V system or is not recommended using a 48V circuit...

    3.3V Microcontroller pin protection circuit.

    Hey all! :) I was looking for a solution to protect the analog pins of the ESP32 microcontroller. My circuit can produce voltages up to 5V and the analog pins of the ESP32 can only withstand 3.3V max. I found a solution online (picture attached) but I don't understand how the circuit works. I...

    Ideas for Arduino Pin Protection - Static Shock

    As the title suggests, I'm looking for some methods that would best work on helping to protect an Arduino (Due more specifically) from being damaged from static shocks. About the setup: I have an Arduino Due in a chair which is connected to many external devices using up about 14 different...

    What is the best, and most handy way to add a fast short current protection to SparkFun Toshiba TB6612FNG?

    Toshiba is almost %100 efficient, no cooler at 2–2.5A, way ahead than any other thing for such currents. So cheap and as a kit perfect to use daily everywhere by youth. One handy short current topology makes it killer because it is stackable as paralel. You can easily do 100A box without a fan...

    Protection Circuit Design for Sensor

    Hello partners The design that you are going to see next belongs to a sensor that I am building, this sensor will be capable of measuring voltages between 25-40 volts through the ADC of a microcontroller and at the same time feeding on these voltages. A fundamental part of every sensor is to...

    Understanding power protection circuit in Raspberry Pi

    The attached schematic is taken from the Raspberry Pi drawing. I am trying to understand how it works and I am pretty much stuck with it. I guess the purpose of the resettable PTC fuse and the TVS diode is clear, being as overvoltage protection. It looks quite obvious that the transistors are...

    Fast acting device to protect a high current 6/12V charger during short circuit?

    Hello, Which device best protects the rectifier and electronics inside an older style car battery charger? I have seen some manufacturers use an ATC blade fuse but I'm not sure if that will act fast enough to protect the circuits. I came across another device too, it's a Bussmann Circuit...
