Abstract
An integral multifunction chip is provided. The integral multifunction chip includes an electronic fuse and an interface fuse. The interface fuse and the electronic fuse are disposed in parallel and integrated in a single chip. In a case where only a single chip is provided, the integral multifunction chip of the present disclosure can be selectively operated in a working mode of the electronic fuse or the interface fuse, so that convenience of use of the integral multifunction chip can be improved.
Claims4
An integral multifunction chip, comprising:
- an electronic fuse;
- and
- an interface fuse connected to the electronic fuse in parallel;
- wherein a relationship between a voltage and a current is positively or negatively correlated when the integral multifunction chip is operated in a working mode of the electronic fuse;
- wherein, when the integral multifunction chip generates a snapback at a voltage between 14V and 25V and a current between 0A and 0.68A, a working range of the integral multifunction chip is in a large current interval greater than 1A;
- wherein, when an input current of the interface fuse is 0, and an input voltage of the interface fuse is between 14V and 20V, the interface fuse provides a low resistance;
- wherein, when the input current of the interface fuse is between 0A and 0.1A, and the input voltage of the interface fuse is about 20V-25V, the interface fuse provides a high resistance greater than the low resistance.
