Power supply discharging control device, circuit and control method thereof

Abstract

The invention relates to a power supply discharging control device, a circuit and a control method thereof. The power supply discharging control device is used for a computer system. The power supplydischarging control device includes a control unit for generating a control signal corresponding to a pin signal of the computer system. And a discharging unit coupled to the control unit is used forexecuting a power supply discharge operation of the computer system according to the control signal; wherein the pin signal is generated when the computer system shuts down normally or when the computer system shuts down abnormally. The invention is used for a computer system to execute power discharging operation according to pin signal of computer system when computer system is shut down normally or abnormally, so as to avoid computer system not to continuously consume energy when computer system is shut down, and to avoid abnormal situation when computer system is restarted.

Description

technical field [0001] The invention relates to a power supply discharge control device, a circuit and a control method thereof, in particular to a power supply discharge control device, a circuit and a control method thereof according to a signal of a computer system. Background technique [0002] When a computer system trips or loses power for unknown reasons, AC loss may occur. If the Basic Input / Output System (BIOS) of the computer system is set to automatic for power management, and the internal design of the power supply of the computer system cannot completely discharge the residual power of the backup power within a certain period of time Under the circumstances, when the power supply of the computer system is restored and the computer system is restarted, the basic input and output system of the computer system may make a wrong judgment due to the residual power supply, which may lead to wrong operations. In this case, the wrong operation of the computer system may...

Problems solved by technology

[0002] When the computer system has a power trip or power failure for unknown reasons, it may cause AC loss (AC Loss)

If the Basic Input / Output System (BIOS) of the computer system is set to automatic for power management, and the internal design of the power supply of the computer system cannot completely discharge the residual power of the backup power within a certain period of time Under the circumstances, when the power supply of the computer system is restored and the computer system is restarted, the basic input and output system of the computer system may make a wrong judgment due to the residual power supply, resulting in erroneous operations

In this case, the wrong operation of the computer system may violate the power management settings of the computer system, resulting in abnormal operation of the computer system when the power is restored

[0003] Therefore, how to effectively solve the above-mentioned problems, so as to avoid misjudgment by the computer system and cause wrong actions when the computer system is turned on, has become an important subject in this technical field.
