Power discharge control system
First Claim
1. A power discharge control system for eliminating residual voltage of at least an electronic component in an electronic device, comprising:
- a control IC for outputting first electrical signals of a first level and a second level respectively corresponding to power on and power off commands of the electronic device;
a power supply electronically connected to the control IC and the at least an electronic component, wherein the power supply receives the first electrical signal outputted by the control IC, so as to accordingly provide or terminate at least an operation power to the at least an electronic component, and delays outputting a second electrical signal which is equivalent to the first electrical signal level;
a logic judgment module coupled to the control IC and the power supply, wherein the logic judgment module receives the first electrical signal outputted by the control IC as well as the second electrical signal outputted by the power supply, executes logic operation process, and outputs a third electrical signal of a third level when at least one of the first electrical signal and the second electrical signal is at the first level and outputs a third electrical signal of a fourth level when both the first electrical signal and the second electrical signal are at the second level; and
at least a discharge module, for receiving the third electrical signal outputted from the logic judgment module, and to determine a discharge process to be skipped when the third electrical signal is at the third level and the discharge process to be executed when the third electrical signal is at the fourth level.
