Abstract
Fuse programming circuits, devices and methods. In some embodiments, a fuse circuit can include a fuse pad configured to receive a voltage, a fuse having a first end coupled to the fuse pad and a second end coupled to a switching element configured to enable a current to pass from the fuse pad to a ground potential.
Claims20
A radio-frequency module comprising:
- a semiconductor die including an integrated circuit;
- and
- a fuse circuit including a fuse pad configured to receive a voltage, a fuse having a first end coupled to the fuse pad and a second end coupled to a switching element configured to enable a current to pass from the fuse pad to a ground potential, and a fuse state sensing circuit coupled to the second end of the fuse and configured to apply a sense current to the second end of the fuse such that the sense current flows through the fuse to the fuse pad.
An electronic module comprising:
- a packaging substrate configured to receive a plurality of components, including a semiconductor die including an integrated circuit;
- and
- a fuse circuit including a fuse pad configured to receive a voltage, a fuse having a first end coupled to the fuse pad and a second end coupled to a switching element configured to enable a current to pass from the fuse pad to a ground potential, and a fuse state sensing circuit coupled to the second end of the fuse and configured to apply a sense current to the second end of the fuse such that the sense current flows through the fuse to the fuse pad.
