DESCRIPTION
The UCC3919 family of Hot Swap Power Managers provide complete 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 compatible L/R pin. In one mode, when a fault occurs the IC repeatedly tries to reset itself at a user defined rate, with...
