Abstract

An overcurrent protection device and an overcurrent protection method for an electronic module are disclosed. In some embodiments, an overcurrent protection system for an electronic circuit may be implemented. The system may include a detection unit configured to detect an overcurrent condition associated with the electronic circuit and generate an overcurrent signal indicative of the overcurrent condition. The system may further comprise an energy consumption system in communication with the detection unit. The energy dissipating system may be configured to dissipate electrical energy to reduce current in a path associated with said electronic circuit when said overcurrent signal is received. The energy consuming system may be further configured to not consume current when the overcurrent signal ceases.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, and more specifically, to an overcurrent protection device for an electronic module and a corresponding overcurrent protection method. Background technique [0002] In various electronic devices such as tablet computers, smart phones, music players, etc., there are electronic modules such as voltage converters, power amplifiers, displays, etc., each of which has a rated current. When the current flowing in the electronic module exceeds the rated current, the electronic module will be burned out and cannot work. Therefore, in the electronic module, an overcurrent protection device needs to be provided to protect the entire electronic module when the current flowing through it is too large. [0003] The various electronic modules need power supply to work. Conventional overcurrent protection devices can achieve overcurrent protection by interrupting the connection of the ele...
