Hello,
Regarding the MP5991 Hot-Swap Intelli-Fuse I would like to know what the reverse current specifications are? Does the device incorporate a blocking FET to prevent reverse current? If not, I assume there is a body diode but it is not shown in the Functional Block Diagram (Figure 5)?
Regards,
Steve
HI @sslupsky,
Welcome and thanks for reaching out to the MPS Forum. I wanted to acknowledge and let you know I am looking into this with our internal team to get those specification values for you.
In the meantime, I’d like to let you know our MP501x series of parts has reverse current specifications if they will fit your application.
Filtering under Special Features → Reverse Current Blocking will show you the parts with those features.

Additionally, for your information I have attached a resource regarding different reverse current/voltage protections. Designing a Reverse Polarity Protection Circuit (Part I) | Article | MPS
Thanks for letting me know you are looking into this. I recall looking at the MP5023 as well but the datasheet similarly does not show a blocking FET and does not illustrate the body diode.
