FETs in the current path need to have very low on-resistance to ensure very low on-loss.
eFuse protection modules in the related technology have a plurality of external signals, and eFuse chips and peripheral resistance and capacitance occupy more space of a main board, so that originally tense board-level space is more difficult to distribute.
In addition, the eFuse protection module in the related art has low flexibility in configuration, and for the same product, different configurations can be selected according to different application scenes, because the conventional eFuse protection module configuration method is selected by the method of loading or not loading PCBA (printed circuit board (Printed Circuit Board, PCB)) during the whole process of producing PCBA (printed circuit board) blank board through SMT (surface mount technology) or Dual in-line Package (DIP) plug-in, the PCBA is short, and some of the eFuse protection modules do not need the application scenes of the protection module, and because the PCBA is shared by the same main board during production, the space on the main board still has to be occupied by the eFuse protection module.
In order to overcome the defects, the invention provides the connector, the electronic safety device and the board card, and the connector is arranged on the board card, so that eFuse chips and peripheral circuits thereof can be prevented from being arranged on the board card, the occupation of the area of the board card can be effectively reduced, the electronic safety device can be selected according to the requirement, and the flexibility of product configuration can be increased.
