description
The UCC3923 family of devices are Hot-Swap Power Managers for use with negative power supplies. These
devices are optimized for use in systems with nominal –48-V supplies, but are fully functional over a supply
range of –20 V to –200 V. These devices can be used both on plug-in cards and on back-planes to limit inrush
current, control load turnon and turnoff, report faults, isolate faulty loads, and sequence downstream dc-to-dc
converters.
The UCC3923 offers the basic features of controlled turnon, load current ramping, and logic output of fault status
in a tiny 8-pin package. The UCC3924 adds undervoltage protection, two insertion detection pins, power-good
sensing, one output for downstream converter enabling, and a reference for cascoding, in a 14-pin package.
The UCC3925 has all of the previously noted features plus overvoltage protection and supply sequencing for
up to five downstream converters in a 20-pin package.
