UCC1919 Datasheet | Unitrode

FEATURES - Precision Fault Threshold - Charge Pump for Low RDSON High Side Drive - Differential Sense Inputs - Programmable Average Power Limiting - Programmable Linear Current Control - Programmable Fault Time - Fault Output Indicator - Manual and Automatic Reset Modes - Shutdown Control w/Programmable Softstart - Undervoltage Lockout - Electronic Circuit Breaker Function DESCRIPTION The UCC3919 family of Hot Swap Power Managers provide plete power management, hot swap, and fault handling capability. The UCC3919 features a duty ratio current limiting technique, which provides peak load capability while limiting the average power dissipation of the external pass transistor during fault conditions. The UCC3919 has two reset modes, selected with the TTL/CMOS patible L/R pin. In one mode, when a fault occurs the IC repeatedly tries to reset itself at a user defined rate,...
