UCC2915DP - Power Control/Management
Features Built-in 0.15-W Power MOSFET
7 V to 15 V operation Digitally programmable current limit from 0 A to 3 A
100-mA ICC Disabled Programmable Time Programmable Startup Delay Fixed 2% Duty Cycle Thermal Shutdown Fault Output Indicator Low thermal resistance packaging
The UCC3915 programmable hot-plug power manager provides complete power management, hot-plug capability, and circuit breaker functionality. The only external components required to operate the device, other than power bypass, fault timing capacitors, CT. All control and housekeeping functions are integrated and externally programmable. These include: fault current level, maximum output current sourced, maximum fault time, and start-up delay. An internally fixed 2% duty cycle limits the average output power during a constant fault. The built-in 4-bit DAC allows programming of the fault level current from 0 A to 3 A with a resolution of 0.25. "The IMAX control pin is set to 1 above the maximum sourcing trip level, or a full output current of 4 to quickly charge the output capacitor. (continued)
