ZHCSI22F October 2017 – December 2021 TPS2662
TheTPS26624 and TPS26625 eFuses feature fully integrated input as well as output reverse polarity protection. The internal FETs of the eFuse turn OFF during the output reverse polarity event and protects the upstream circuits from negative voltage that can appear at the output of the eFuse due to field miswiring at the output side with an external isolated power supplies. Figure 9-5 illustrates the performance during output side reverse polarity event with V(IN) un-powered and Figure 9-6 illustrates the performance with V(IN) powered. Figure 9-7 illustrates the output recovery performance after the reverse polarity is removed.
