ZHCSI22E October 2017 – August 2019 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 35 illustrates the performance during output side reverse polarity event with V(IN) un-powered and Figure 36 illustrates the performance with V(IN) powered. Figure 37 illustrates the output recovery performance after the reverse polarity is removed.
