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 pro-
vides peak load capability while limiting the average power dissipa-
tion of the external pass transistor during fault conditions. The
UCC3919 has two reset modes, selected with the TTL/CMOS com-
patible L/R pin. In one mode, when a fault occurs the IC repeatedly
tries to reset itself at a user defined rate, with user defined maximum
output current and pass transistor power dissipation. In the other
mode the output latches off and stays off until either the L/R pin is re-
set or the shutdown pin is toggled. The on board charge pump circuit
provides the necessary gate voltage for an external N-channel power
FET.
