Abstract

A described example includes a circuit (100). The circuit (100) can include a current sense circuit (106) having a sense input and a sense output, in which the sense input is coupled to an input terminal. A comparator (114) has a first comparator input, a second comparator input, and a comparator output, in which the first comparator input is coupled to the sense output, the second comparator input is coupled to a threshold terminal, and the comparator output is coupled to a fuse terminal. A current programming circuit (128) has a current input and a current output, in which the current input is coupled to the sense output. A first circuit (134) is coupled between the sense output and a ground terminal. A second circuit (136) is coupled between the current output and the ground terminal.
