15-V Programmable Hot Swap Power Manager

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 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 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.
