The UCCx917 family of positive-floating hot-swap managers provides complete power management, hot-swap, and fault handling capability. The voltage limitation of the application is only restricted by the external component voltage limitations. The IC provides its own supply voltage via a charge pump referenced to VOUT. The onboard 10-V shunt regulator protects the IC from excess voltage. The IC also has catastrophic fault indication to alert the user that the ability to shut off the output NMOS has been bypassed. All control and housekeeping functions are integrated and externally programmable. These include the fault current level, maximum output sourcing current, maximum fault time, soft-start time, and average NMOS power limiting.
