Circuit for preventing unintentional power off of mobile terminal and method therefor |
摘要 |
A circuit for preventing temporary power off of a portable electric device by loose battery contact. The circuit includes a power charge unit (210) for receiving a first state signal (OFF_STATE_WR) representing a state of the mobile terminal from a main chip set (MSM), changing or maintaining a state of a second state signal (OFF_STATE_RD) according to the state of the first state signal (OFF_STATE_WR), and outputting the second state signal (OFF_STATE_RD); an enable power signal generator (220) for generating a power-on enable (EN) signal by receiving the second state signal (OFF_STATE_RD) or by receiving a power key input signal (ON_SW); and a voltage control unit (230) for supplying electric power to the main chip set (MSM) of the mobile terminal in response to the power-on enable signal (EN) by controlling the electric power to the mobile terminal. The circuit can increase packaging efficiency. <IMAGE> |
