Abstract:
A fuse sensing circuit is disclosed. Embodiments include: providing a sense input terminal; providing a sense output terminal; and providing first and second capacitors that are configured to charge and discharge based on the sense input terminal, wherein the first and second capacitors are further configured to discharge current to a fuse unit cell, and the sense output terminal is configured to indicate a fuse state of the fuse unit cell based on the discharging of the first and second capacitors. Embodiments include the indicated fuse state being based on a discharge rate difference between the discharging of the first capacitor and the discharging of the second capacitor.
