Built-in battery controller for personal telecommunication device
First Claim
1. A battery controller, comprising:
- a push switch operable to be switched on and off;
a power switch connected to the push switch and operable to allow a leakage current to flow through the power switch based on input from the push switch;
a battery pack including a battery and a protection circuit module (PCM) for turning off the battery when the leakage current flows through the power switch; and
a charging circuit for charging the battery pack.

Abstract
A built-in battery controller for a personal telecommunication device. The battery controller includes a push switch that is switched on and off by a user, a power control unit that is connected to the push switch and allows a leakage current to flow through the power switch, a battery pack including a protection circuit module (PCM) for turning off the battery when the leakage current flows through the power switch under the control of the power control unit, and a charging circuit for charging the battery pack. The battery controller can be simply operated and can more reliably turn off the battery without affecting the outer appearance of the device.
