Abstract

The invention provides an electronic product charging function test system. The electronic product charging function test system comprises a first switching system, a second switching system and a reset chip; the first switching system is used for outputting a charging voltage and sending out a prompt tone; the second switching system is electrically connected with the first switching system to acquire the charging voltage, and the second switching system is electrically connected with an electronic product to charge the electronic product and acquire a voltage value of a battery port of the electronic product; the input end of the reset chip is electrically connected with the second switching system to acquire the voltage value of the battery port of the electronic product; and the resetend of the reset chip is electrically connected with the first switching system, and according to the acquired voltage value of the battery port of the electronic product, judges whether to generate areset signal to the first switching system so as to trigger the first switching system to switch the charging voltage and send out the prompt tone.

Description

technical field [0001] The invention relates to a charging function testing system for electronic products, in particular to a charging function testing system for electronic products with an overvoltage protection function. Background technique [0002] With the rapid development of science and technology, more and more electronic products appear in people's daily life, such as mobile phones, PDA (Personal Digital Assistant, personal digital assistant), notebook computers, etc. have become important communications in people's lives. and entertainment tools. The charging function is a function that most electronic products have at present. This type of electronic product needs to go through a charging test before leaving the factory to check whether the charging function of the product is normal. [0003] However, the existing electronic product charging function test systems usually do not have an overvoltage protection function, and the electronic product is easily damage...
