AI Technical Summary
In miniaturized energy storage products, the space inside the device cavity is limited, and the heat generated during the operation of the device is difficult to dissipate, resulting in the temperature being maintained at a high level for a long time. Existing protection circuits are subjected to large current surges when starting with a large load, which leads to power supply overload operation and affects product reliability and service life.
A protection circuit is provided that dynamically adjusts the current limiting threshold according to temperature through a reference signal generation circuit, allowing a large starting current to pass through at low temperatures and adaptively adjusting the current limiting threshold as the temperature rises to reduce overheating damage. The circuit includes an output switching circuit, a switching circuit, a sampling circuit, a comparison circuit, and a reference signal generation circuit to achieve adaptive current limiting protection.
Provide sufficient current during the initial load startup to avoid startup failure, and reduce overheating damage caused by overload operation after normal operation, thereby improving the safety and reliability of the energy storage system.
