UCC3919 3-8V 单路热插拔 IC 商用温度

UCC3919 描述

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 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 reset or the shutdown pin is toggled. The on board charge pump circuit provides the necessary gate voltage for an external N-channel power FET.
