The UCC3915 programmable hot swap power manager provides complete power-management, hot-swap
capability, and circuit breaker functions. The only external component required to operate the device, other than
power supply bypassing, is the fault-timing capacitor, CT. All control and housekeeping functions are integrated,
and externally programmable. These include the fault current level, maximum output sourcing current,
maximum fault time, and startup delay. In the event of a constant fault, the internal fixed 2% duty cycle ratio limits …
