Problems solved by technology

[0003] The traditional P.G signal detection is applied in the PC industry. At the same time, the detection method is to detect the input and detect the 5VSB signal; the existing technology is only suitable for the application in the field of PC. The output is abnormal, and the P.G fault signal cannot be output

Abstract

The invention discloses a dual output power supply Power Good signal control circuit and electronic equipment, which belong to the field of power supply control. The dual output power supply Power Good signal control circuit includes: a first input terminal connected to the dual output power supply The first power supply of the first road; the second input terminal is connected to the second power supply of the dual output power supply; the P.G signal generation circuit is used to generate the P.G signal according to the states of the first power supply and the second power supply, so The level status of the P.G signal indicates whether it is a normal signal; the output terminal is used to output the P.G signal to the power supply monitoring system. The present invention can identify the power module by monitoring the P.G signal; in order to maintain in time, ensure that the dual backup power module always has a backup function, and the display screen will not be unable to display due to power failure in important display scenes.

Description

technical field [0001] The invention belongs to the field of power supply control, and more particularly relates to a dual output power supply Power Good signal control circuit and electronic equipment. Background technique [0002] Power Good signal is abbreviated as P.G or P.OK signal. After the switching power supply is started, if the input voltage is within the rated range, and the DC output voltage of each channel reaches the allowable value, then after a certain time delay, the P.G circuit will issue a "power supply is normal" signal (P.OK is high level). When the power input is abnormal or the output voltage is abnormal, the power supply will send a "power failure" signal (P.OK is low level). If the P.G signal cannot be detected on the computer or server, it will cause the computer to fail to boot. Monitoring or related control can be done by detecting the P.G signal. [0003] The traditional P.G signal detection is used in the PC industry, and the detection meth...
