UCC2912 可编程热插拔开关电源管理器
UCC2912 描述
The UCC3912 family of hot swap power managers provides complete power management, hot swap capability, and circuit breaker functions. The only component required to operate the device, other than 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 3% 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 fault level when driven low, and to a full 4 A when driven high for applications which require fast output capacitor charging
