Abstract
Provided are a charging circuit and a power supply including the same. The charging circuit includes a charging unit connected to a power source and a load, and configured to receive an input voltage applied from the power source, a current limiting unit connecting the power source to the charging unit, and an electronic fuse connecting the power source to the charging unit in parallel with the current limiting unit.
Claims18
A charging circuit comprising:
- a charging unit connected to a power source and a load, and configured to receive an input voltage applied from the power source;
- a current limiting unit connecting the power source to the charging unit;
- and
- an electronic fuse connecting the power source to the charging unit in parallel with the current limiting unit,
- wherein the input voltage is applied through the current limiting unit when the electronic fuse is in a first state, and through the electronic fuse when the electronic fuse is in a second state,
- a state of the electronic fuse transitions from the first state to the second state based on an initial charging completion condition being satisfied while the electronic fuse is in the first state, and
- the state of the electronic fuse transitions from the second state to the first state based on an abnormality detection condition being satisfied while the electronic fuse is in the second state.

A power supply comprising:
- a power source configured to supply a power to a load;
- a charging unit connected to the power source and the load, configured to receive an input voltage applied from the power source, and configured to supply the power to the load when power delivery from the power source to the load is interrupted;
- a current limiting unit connecting the power source to the charging unit;
- and
- an electronic fuse connecting the power source to the charging unit in parallel with the current limiting unit,
- wherein the input voltage is applied through the current limiting unit when the electronic fuse is in a first state, and through the electronic fuse when the electronic fuse is in a second state,
- a state of the electronic fuse transitions from the first state to the second state based on an initial charging completion condition being satisfied while the electronic fuse is in the first state, and
- the state of the electronic fuse transitions from the second state to the first state based on an abnormality detection condition being satisfied while the electronic fuse is in the second state.
5 more elements
A charging method using a charging circuit, the method comprising:
