Abstract
Embodiments of the present invention provide a charging and power supplying circuit, method and application device, which relate to the field of smart charging, so as to improve efficiencies of battery charging and system power supplying. The charging and power supplying circuit includes a power supplying tributary and a charging tributary. An end of the power supplying tributary is connected to a power supply, and another end is connected to a system. An end of the charging tributary is connected to the power supply, and another end is connected to a battery. A first transistor, a second transistor, a third transistor, a first amplifier, a second amplifier, a third amplifier, a fourth amplifier, a first comparator, a second comparator, a charging controller, a logical switch, an adder and a first control module are connected to the power supplying tributary and the charging tributary.
