1. A fuse detect circuit, comprising:

  • a fuse state detect stage for providing an output signal of a first logic state in response to detecting a fuse is an open circuit, and for providing the output signal of a second logic state in response to detecting the fuse is a short circuit, wherein the fuse state detect stage limits a voltage drop across the fuse to an absolute value independent of a power supply voltage value applied to the fuse detect circuit; and

    a latch stage, coupled to the fuse state detect stage, for latching a logic state of the output signal.
