Abstract

The present invention provides a power chip self-restart device, method and system, including: a power chip and a restart control circuit; two ends of the power chip are respectively provided with an output flag terminal and an enable terminal; the restart control circuit includes: A triode, a second triode, a first capacitor, a second capacitor and a charging resistor; the base of the first triode is connected to the output flag terminal of the power supply chip, and the collector of the first triode is connected to the The first capacitor is connected, the first capacitor is connected to the base of the second transistor, the second capacitor is connected in parallel between the base and the emitter of the second transistor, and the charging resistor is connected in parallel to the second two ends of the capacitor; the collector of the second triode is connected to the enabling terminal of the power chip. The present invention realizes the automatic restart function of the power chip by setting a restart control circuit on the periphery of the power chip, and then triggering the enable signal of the power source to change from high to low, and then returning to normal after a delay.

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...
