The Texas Instruments TPS2393DBT is a hot swap controller optimized for nominal -48V systems. It supports a wide input supply voltage range from -20V to -80V, with transient ratings up to -100V. This device enables live insertion of plug-in cards and modules into powered systems.
Key features include programmable current limit, slew rate control, and undervoltage/overvoltage lockout thresholds. It also provides debounced insertion detection inputs and an open-drain power good output. The TPS2393DBT is housed in a 44-TSSOP package, suitable for surface mounting.
Applications for this hot swap controller include -48V distributed power systems, central office switching, and wireless base stations. Its design facilitates electrical isolation of faulty cards and provides filtered protection against nuisance overcurrent trips.
