Embodiment Construction
[0024] The invention provides a standby circuit of a handheld device and a wake-up method thereof, which can keep the power consumption at a very low level during standby, and at the same time install a low-power sensor at a suitable position of the device to enable the operator to operate the device The transparent wake-up of the system was completed before.
[0025] Transparent wake-up in this article means that after the user picks up the device, the device can automatically sense and wake up. This process is transparent to the user, and the user does not feel the existence of this process.
[0026] The present invention utilizes capacitive touch key sensor (or pyroelectric sensor), CPU with sleep mode and controllable power supply management IC to realize standby transparent wake-up.
[0027] like figure 1 Shown is a schematic circuit structure diagram of a standby circuit of a handheld device according to an embodiment of the present invention. The standby circuit of the...
