Can you explain how the current limit protection circuit works?mariuszoll said:I made a current limit protection circuit at 1A, and I would like to improve it with an overload protection. Could you give me please some ideas how to switch off the mosfet when the load current exceed 1A?
I think you're looking for a "latched overcurrent fault detector". In the article linked to below they use a latching comparator that turns off the FET when the current exceeds the limit. Hopefully that might give you some ideas!mariuszoll said:Beside this current limitation, I would like also, to shut down the circuit when current becomes equal or higher than 1A. If you could give me some ideas how to do it, I would appreciate it.
Overload protection is a safety feature in electrical systems that prevents damage or malfunction caused by excessive current. It is important because it helps to protect equipment and prevent potential hazards such as fires.
Overload protection works by monitoring the amount of current flowing through a circuit. If the current exceeds a predetermined limit, the protection device will trip and interrupt the flow of electricity to prevent damage.
There are several types of devices that can be used for overload protection, including circuit breakers, fuses, and thermal overload relays. Each type has its own unique features and advantages, and the best choice depends on the specific application.
Overload in electrical systems can be caused by a variety of factors, such as too many appliances or devices connected to a single circuit, short circuits, or faulty wiring. It can also occur due to power surges or fluctuations in voltage.
The best way to ensure proper overload protection in an electrical system is to have a professional electrician perform a thorough inspection and make any necessary upgrades or repairs. It is also important to regularly check and maintain all electrical equipment to prevent overload situations.
