Mobile phone apparatus with over voltage protection device
First Claim
1. A mobile phone apparatus comprising:
- a charger configured to supply power to a rechargeable battery comprising a connection portion;
a main telephone device comprising;
a supply power connecting device configured to switch between a first active state of supplying power from the charger to the connection portion of the rechargeable battery and a first inactive state of not supplying power from the charger to the connection portion of the rechargeable battery;
a charger detection device configured to determine whether the charger supplies power;
a supply setting device configured to set the supply power connecting device into the first active state when the charger detection device detects that the charger supplies power;
a rechargeable battery detection device configured to detect whether the connection portion of the rechargeable battery is connected to the main telephone device;
an overvoltage protection device configured to be coupled to the connection portion of the rechargeable battery and configured to switch between a second active state of supplying power output from the connection portion to a device to be protected and a second inactive state of not supplying power output from the connection portion to the device to be protected;
an initialization controller configured to switch the overvoltage protection device into the second inactive state at a startup time; and
a controller configured to control the overvoltage protection device to switch into the second active state when the rechargeable battery detection device detects that the rechargeable battery is connected, after the initialization controller switches the overvoltage protection device into the second inactive state.

Abstract
A mobile phone apparatus is provided. The mobile phone apparatus includes a charger for supplying power to a rechargeable battery including a connection portion and a main telephone unit. The main telephone unit includes a rechargeable battery detection unit which detects whether the connection portion of the rechargeable battery is connected to the main telephone unit; an overvoltage protection unit which is coupled to the connection portion of the rechargeable battery and switches between an active state of supplying power output from the connection portion and an inactive state of not supplying power output from the connection portion; and a controller which controls the overvoltage protection unit to switch the overvoltage protection unit into the active state if the rechargeable battery detection unit detects that the rechargeable battery is connected.

6. A mobile phone apparatus comprising:
-
a charger configured to supply power to a rechargeable battery comprising a connection portion; and a main telephone device comprising; a supply power connecting device configured to switch between a first active state of supplying power supplied from the charger to the connection portion of the rechargeable battery and a first inactive state of not supplying power supplied from the charger to the connection portion of the rechargeable battery; an overvoltage protection device configured to be coupled to the connection portion of the rechargeable battery and configured to switch between a second active state of supplying power output from the connection portion to a device to be protected and a second inactive state of not supplying power output from the connection portion to the device to be protected; an initialization control device configured to switch the supply power connecting device into the first active state and to switch the overvoltage protection device into the second inactive state at a startup time an off setting device configured to control the supply power connecting device to switch the supply power connecting device into the first inactive state after a first period of time from a time when the initialization control device switches the supply power connecting device into the first active state; and a controller configured to control the overvoltage protection device to switch into the second active state when a predetermined voltage is supplied from the connection portion of the rechargeable battery after a second period of time from a time when the supply power connecting device is switched into the first inactive state, and the controller is configured to control the initialization control device to switch the supply power connecting device into the first active state when the predetermined voltage is not supplied from the connection portion of the rechargeable battery after the second period of time from the time when the supply power connecting device is switched into the first inactive state. - View Dependent Claims (7, 8)
