Abstract
A parallel e-fuse device including: a first e-fuse to receive an input voltage and transfer a first fuse current to an output terminal; and a second e-fuse to receive the input voltage and transfer a second fuse current to the output terminal, the first e-fuse includes: a power transistor to control the first fuse current according to a gate voltage; a clamp amplifier to provide a charging current to charge a gate of the power transistor, the charging current being obtained by monitoring a feedback voltage; a balance amplifier to provide a first sinking current to discharge the gate of the power transistor, the first sinking current being obtained by comparing a current sensing signal with a current monitoring signal, wherein the clamp amplifier generates the charging current according to a differential voltage between the feedback voltage and a reference voltage.
