PORTABLE ELECTRONIC APPARATUS AND CIRCUIT AND METHOD FOR CHARGING RECHARGEABLE BATTERY THEREOF
First Claim
1. A method of providing operating current to a portable electronic apparatus, the method comprising:
- connecting a first connection terminal of the portable electronic apparatus to a second connection terminal of a host;
detecting interface type of the second connection terminal;
if the interface type of the second connection terminal is USB 2.0, providing a first operating current to the portable electronic apparatus for performing data read/write by the host, and providing a second operating current to the portable electronic apparatus by an internal rechargeable battery of the portable electronic apparatus;
if the interface type of the second connection terminal is USB 3.0, providing a third operating current to the portable electronic apparatus for performing data read/write by the host, and selectively performing a charge process on the rechargeable battery by the third operating current; and
if the interface type of the second connection terminal is Wi-Fi, providing a fourth operating current to the portable electronic apparatus by the rechargeable battery.

Abstract
In a method of providing operating current to a portable electronic apparatus, a first connection terminal of the portable electronic apparatus is connected to a second connection terminal of a host, and interface type of the second connection terminal is determined. If the interface type is USB 2.0, the host provides a first operating current to the portable electronic apparatus for performing data read/write, and an internal rechargeable battery of the portable electronic apparatus provides a second operating current to the portable electronic apparatus. If the interface type is USB 3.0, the host provides a third operating current to the portable electronic apparatus for performing data read/write, and the third operating current selectively performs a charge process on the rechargeable battery. If the interface type is Wi-Fi, the rechargeable battery provides a fourth operating current to the portable electronic apparatus.
