CIRCUITS FOR PROTECTING AGAINST ACCIDENTAL FUSE ACTIVATION

Abstract: this disclosure relates to circuits, methods, and devices designed to mitigate accidental activation of fuses. accidental fuse activation can occur due to power supply transients, electrical overstressing, etc. a fuse system described herein can include a first fuse programming switch connected between a shared power supply and programming pad and a fuse, and a second fuse programming switch connected between the fuse and a ground or other voltage potential pad. the system can utilize these switches to selectively enable or isolate the fuse during programming or regular operation, thereby protecting the fuse from unintended voltage spikes or transients.
