发明名称 Power on/off control circuit and method
摘要 An apparatus for turning power to a device on and off is disclosed. The apparatus comprises a first signal input, a second signal input, a first charge output electrically connected with the first signal input, a transistor electrically connected with the second signal input, and a second charge output electrically connected with the transistor. The first charge output, when the first signal input and second signal input are powered on, electrically ramps up a first portion of the device. This ramp up of the first portion draws from current available to ramp up a second portion of the device. The second charge output is, thus, provided. The second charge output, when the first signal input and second signal input are powered on, electrically charges the transistor and the transistor electrically ramps up the second portion of the device concurrently with the ramp up of the first portion.
