Lithium battery charger is a charger specifically designed for charging lithium-ion batteries. Lithium ion batteries have high requirements for chargers and require circuit protection, so lithium battery chargers usually have high control precision and can charge lithium-ion batteries with constant current and voltage.

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 transistor, which can safely and effectively charge a single lithium battery quickly. Its biggest feature is that it can still achieve very low power dissipation without the use of inductance. It uses eight pins μ MAX packaging. The charging control accuracy reaches 0.75%, which can achieve pre charging. The maximum charging time is limited to providing secondary protection for lithium batteries. The float charging method of the lithium battery charger can maximize the battery capacity

Integrated computer power supply

The lithium battery charger can automatically detect the charging power supply and automatically turn off when there is no power supply to reduce battery leakage. After starting the fast charge, open the external P-type Field-effect transistor. When it is detected that the battery voltage reaches the set threshold, enter the pulse charging mode. The opening time of the P-channel FET will be shorter and shorter. When the charging is completed, the LED indicator will flash at 12% cycle. When the charging power supply and battery are within the normal operating temperature range, inserting the battery will initiate a charging process; The condition for the end of charging is that the average pulse charging current reaches 1% of the fast charging current, or the time exceeds the preset charging time on the chip.
