Abstract

The invention provides a self-starting device, method and system for a power supply chip. The self-starting device comprises the power supply chip and a restarting control circuit, wherein two ends ofthe power supply chip are respectively provided with an output mark end and an enable end. The restart control circuit comprises a first triode, a second triode, a first capacitor, a second capacitorand a charging resistor. The base electrode of the first triode is connected with the output mark end of the power supply chip, the collector electrode of the first triode is connected with the firstcapacitor, the first capacitor is connected with the base electrode of the second triode, the second capacitor is connected between the base electrode and the emitting electrode of the second triodein parallel, and the charging resistor is connected to the two ends of the second capacitor in parallel. And the collector electrode of the second triode is connected with the enabling end of the power supply chip. According to the invention, the restart control circuit is arranged at the periphery of the power supply chip, and then the enable signal of the power supply is triggered from high to low, so the delay returns to normal, and the automatic restart function of the power supply chip is realized.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a power supply chip self-restarting device, method and system. Background technique [0002] With the development of power supply technology, the requirements for the stability of the power supply are also getting higher and higher. If the system power supply does not have a restart function, it will cause huge losses in the case of a system crash. In order to ensure the stability and safety of the power system, it is very important to restore and restart the power supply, which can solve some simple fault problems in a short time. [0003] Such as figure 1 As shown, in servers or other electronic devices, the power chip often triggers automatic protection due to abnormal back-end load. In order to lock the current power state, it needs to be powered on again or restarted through the enable signal to restore the power supply. Contents of the invention [00...
