Users of battery powered equipment expect safeguards to prevent damage to the internal electronics in the event of reverse battery installation, accidental short circuiting, or other inappropriate operation. These safeguards can be either mechanical or electronic.
Battery protection is required to prevent damage due to high current discharge, overcharge, temperature rise, etc. The protection can be built into the structure of the battery, or the external protection circuit can be used to disconnect the battery. Some batteries come with safety features within the battery structure.
That is why we design our battery protection ICs to detect a variety of fault conditions including overvoltage, undervoltage, discharge overcurrent and short circuit in single-cell and multi-cell batteries, so you can enhance the safety of your battery pack.
In addition, a fuse cuts the current if the skin temperature of any cell approaches 90°C (194°F). To prevent the battery from over-discharging, a control circuit cuts off the current path at about 2.20V/cell. Each cell in a string needs independent voltage monitoring. The higher the cell count, the more complex the protection circuit becomes.
Battery protection circuits / IC solutions and reference designs that allow easy design-in and ensure safe charging and discharging - prevent damage and failures.
