Other Parts Discussed in Thread: TL7700-SEP
I plan to install a rad hardened undervoltage protection circuit for our NOT rad hardened OBC subsystem. It's supply voltage is 3.3V. For this application, I am eyeing a radhard eFUSE (TPS7H2201-SP ) and a radhard supervisory IC (TL7700-SEP).
Both of them can cause an OBC reset during an undervoltage event. The eFUSE shuts itself down, thus shutting down / resetting the OBC. On the other hand, the supervisory IC sends a reset signal to the OBC to reset itself; hence, resetting itself.
However, I am still quite confused with the difference of the two given that they function the same way. Could your product engineer please tell me which one is better for my application? He might see something I don't.
I understand that the space-graded components are not abundant, thus I think I am willing to entertain military-graded components as well.
I am also done reading this TI paper: www.ti.com/.../slyy167.pdf. But I am still a bit confused.
