The lithium-ion battery charger is externally connected with a current limiting charging power supply and a P-channel FET, which can safely and effectively charge a single lithium-ion 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 and has overvoltage protection and temperature protection functions. The maximum charging time is limited to providing secondary protection for lithium-ion batteries. The floating charging method of lithium-ion battery chargers can maximize the battery capacity.
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. The lithium-ion 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.
