Abstract

Provided herein are approaches for determining a status of a fuse. In some embodiments, a system may include a first fuse electrically connected to a first node and to a first resistor, and a second fuse electrically connected to a second node and a second resistor, wherein the first and second fuses are in parallel connection to a same port of a multiplexer. The system may further include a controller communicably connected with the multiplexer, the controller operable to read a voltage level of the first and second nodes.
