1. A protection circuit module of a secondary battery, comprising:
- a printed circuit board in which at least one wiring pattern is formed;
a conductive pad that is coupled to the at least one wiring pattern, and is electrically coupled to the secondary battery; and
a semiconductor package that is soldered on the at least one wiring pattern and blocks a charging path or a discharging path of the secondary battery if a voltage of the secondary battery is in overcharged or over-discharged ranges.

Abstract
A protection circuit module includes a printed circuit board in which at least one wiring pattern is formed, a conductive pad that is coupled to a wiring pattern of the printed circuit board, and is electrically coupled to a rechargeable battery, and a semiconductor package that is soldered on the wiring pattern of the printed circuit board, so that if the voltage of the rechargeable battery is in the overcharged or over-discharged state, the semiconductor package selectively blocks a charging path or a discharging path of the rechargeable battery.

12. A battery pack comprising:
-
a rechargeable battery; a pack terminal that is coupled to the rechargeable battery in parallel; and a protection circuit module, that is coupled to the rechargeable battery, to sense a voltage of the rechargeable battery, and to block an overcharging or an over-discharging of the rechargeable battery, wherein the protection circuit module includes; an integrated circuit that senses the overcharging or the over-discharging of the rechargeable battery and outputs a signal that blocks the charging and the discharging thereof; and a charging switch and a discharging switch that selectively block the charging and discharging paths by the output signal, and wherein the integrated circuit, the charging switch, and the discharging switch are formed as one semiconductor package. - View Dependent Claims (13, 14, 15, 16)

17. A single device package to control charging and discharging of a rechargeable battery, comprising:
-
a circuit device to detect a voltage of the rechargeable battery and to output a control signal based on the detected voltage, and which is formed on a first mounting plate; a charging switch to regulate the charging of the rechargeable battery based on the control signal, which is formed on a second mounting plate separated from the first mounting plate; a discharging switch to regulate the discharging of the rechargeable battery based on the control signal, which is formed on the second mounting plate; and a connecting wire to electrically connect the charging switch to the circuit device, which is not interposed therebetween. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
