Output voltage stabilizing system

Номер: CN115967066A
Принадлежит:

The invention relates to an output voltage stabilizing system, and belongs to the technical field of intelligent power utilization. The system comprises a voltage-stabilized source, a voltage-stabilized circuit and a current-limiting protection circuit, the voltage-stabilized source has two outputs, one output is connected to an external module through the voltage-stabilized circuit, the other output is connected with an MCU, and the enabling end of the current-limiting protection circuit is connected to the voltage-stabilized source through a first voltage division circuit. When the voltage output by the first voltage division circuit is smaller than the enabling action voltage threshold value, the voltage output is turned off, whether the maximum current flowing through the external module connected with the stabilized voltage supply is abnormal or not is judged according to the set protection action current value, the voltage output is turned off under the abnormal condition, and when ...
