Abstract
The present invention provides an electronic device, a power supply control chip and a power supply control method. The electronic device includes: at least one element (10); a rechargeable battery (12); an adapter socket (14); a first processing circuit (16) having a first operation state and a second operation state; a power supply judgment parameter acquisition module (18) configured to acquire a power supply judgment parameter; and a control module (20) configured to control the first processing circuit to operate in the first or second operation state based on the power supply judgment parameter. In the first operation state, the first processing circuit (16) is configured to convert a first electrical signal output from a adapter into a second electrical signal and charge the rechargeable battery (12) with the second electrical signal. In the second operation state, the first processing circuit (16) is configured to convert a third electrical signal output from the rechargeable battery (12) into a fourth electrical signal and supply power to the at least one element (10) with the fourth electrical signal. With the electronic device, the power supply control chip and the power…
