Unitrode UCC2915
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. These include the fault current level, maximum output sourcing current, maximum fault time, and startup delay.| Part No. | UCC2915 |

ą UCC2915, UCC3915 15ĆV PROGRAMMABLE HOT SWAP POWER MANAGER D Integrated 0.15-Ω Power MOSFET D 7-V to 15-V Operation D Digital-Programmable Current Limit from 0 A to 3 A D 100-µA ICC When Disabled D Programmable On Time D Programmable Start Delay D Fixed 2% Duty Cycle SLUS198C – FEBUARY 2000 - REVISED - JUNE 2001 D Thermal Shutdown D Fault-Output Indicator D Maximum-Output Current Can Be Set to 1 A Above the Programmed-Fault Level or to a Full 4 A D Power SOIC and TSSOP, Low Thermal Resistance Packaging description All control and housekeeping functions are integrated, and externally programmable. In the event of a constant fault, the internal fixed 2% duty cycle ratio limits average output power. The internal 4-bit DAC allows programming of the fault-level current from 0 A to 3 A with 0.25-A resolution. The IMAX control pin sets the maximum-sourcing current to 1 A above the trip level or to a full 4 A of output current for fast output capacitor charging. (continued) block diagram IMAX...
