Lithium battery charger in practical applications

The lithium battery charger has overvoltage protection and temperature protection functions. The lithium battery charger is externally connected with a current-limiting charging power supply and a P-channel field effect tube. It can safely and efficiently charge a single-cell lithium battery. Its biggest feature is that it is not used. In the case of inductance can still achieve very low power dissipation, using 8-pin μMAX package. The charging control accuracy reaches 0.75%, pre-charging can be achieved, the longest charging time limit provides secondary protection for the lithium battery, and the floating charging method of the lithium battery charger can maximize the battery capacity.

The lithium battery charger can automatically detect the charging power, and automatically shut down when there is no power to reduce battery leakage. After starting fast charging, turn on the external P-type field effect tube.When it detects that the battery voltage reaches the set threshold, it enters the pulse charging mode.The time for the P-channel field effect tube to open will become shorter and shorter.When the charging is completed, the LED indicator light It will flash in 12% cycles. When the charging power supply and the battery are within the normal operating temperature range, inserting the battery will start a charging process; the end of charging is that the average pulse charging current reaches 1% of the fast charging current, or the time exceeds the on-chip preset charging time.

Lithium battery charger is a charger specially used to charge lithium ion battery. Lithium-ion batteries have higher requirements for chargers and require protection circuits, so lithium-ion battery chargers usually have higher control precision and can charge lithium-ion batteries at a constant current and constant voltage.
