摘要： A touch controller apparatus configured to sense a gesture performed on an electronic device is provided. The touch controller apparatus includes a touch controller, a system controller, an accelerator sensor, and a proximity sensor. The touch controller is configured to operate in a smart idle mode. The system controller, the accelerator sensor and the proximity sensor are configured to operate in a deep sleep mode. The gesture wakes up the touch controller, and the touch controller wakes up the system controller. The system controller wakes up the accelerator sensor and the proximity sensor to generate a sensing data. The system controller controls the electronic device to change from the smart idle mode to a normal mode according to the sensing data. Furthermore, a method for waking up an electronic device is also provided.
