Problems solved by technology

[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 decreases, the voltage value of the power-on trigger signal will increase, but the standby power consumption will also increase accordingly, and the voltage value of the power-on trigger signal cannot be flexibly adjusted.

Abstract

The invention discloses an electrical device, a standby control circuit and a control method thereof. The standby control circuit is respectively connected with a main chip and a power board of the electrical device, and includes a protection module, a switch module and an adjustment module; the protection module connects the The control signal output by the main chip is output 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 board to start; When the control signal is a second level signal, the switch module outputs a corresponding trigger signal according to the control signal to control the power board to stand by; the adjustment module adjusts the voltage of the trigger signal when the power board is turned on value, thereby effectively reducing the standby power consumption of electrical equipment during standby, and ensuring that the power board can be turned on normally 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...
