Electrical equipment, standby control circuit and control method thereof

Abstract

The invention discloses electrical equipment, a standby control circuit and a control method of the standby control circuit, and the standby control circuit is connected with a main chip and a power panel of the electrical equipment and comprises a protection module, a switch module and an adjustment module; the protection module outputs a control signal output by the main chip to the switch module; when the control signal is a first level signal, the switch module outputs a corresponding trigger signal according to the control signal to control the power panel to be started; when the controlsignal is a second level signal, the switch module outputs a corresponding trigger signal according to the control signal to control the power panel to be standby; and the adjusting module adjusts thevoltage value of the trigger signal when the power panel is started, so that the standby power consumption of the electrical equipment in a standby state is effectively reduced, and the power panel can be normally started according to application requirements.

Description

technical field [0001] The invention relates to the technical field of electrical circuits, in particular to an electrical device, a standby control circuit and a control method thereof. Background technique [0002] No matter whether the current standby control circuit is working or standby, the standby circuit itself will always generate a conduction current, which increases the standby power consumption of the product when it is in standby. [0003] At the same time, when the resistance value of the pull-up resistor in the standby circuit increases, the standby power consumption will decrease, but the voltage value of the corresponding output power-on trigger signal will also decrease, which will cause the power board to fail to turn on; and when the pull-up resistor When the resistance value of the power-on trigger signal decreases, the voltage value of the power-on trigger signal will increase, but the standby power consumption will also increase accordingly, and the vo...
