Abstract
The invention discloses a lithium battery charging circuit. The lithium battery charging circuit comprises a charging management module and a lithium battery. The lithium battery charging circuit further comprises a protective circuit for preventing the lithium battery from overcharging and over-discharging; the protective circuit comprises a lithium battery protecting chip and a switch chip; an anode of an output end of the charging management module is connected to a n anode of the lithium battery and an anode of the power source of the lithium battery protecting chip, and a cathode of the lithium battery is connected to a cathode of the power source of the lithium battery protecting chip and one connecting end of the switch chip; the other one connecting end of the switch chip is connected with a grounding end of the charging management module; the output end of the lithium battery protecting chip is connected with the control end of the switch chip. The circuit has a protective circuit for overcharging and discharging, and is capable of preventing the lithium battery from overcharging and discharging.
