General Description

The HV100/HV101 are 3-pin hotswap controllers available in SOT-223 and MLP packages, which require no external components other than a pass element. The HV100/HV101 contain many of the features found in hotswap controllers with 8 pins or more, and which generally require many external components. These features include undervoltage (UV) detection circuits, power on reset (POR) supervisory circuits, inrush current limiting, short circuit protection, and auto-retry. In addition, the HV100/HV101 use a patent pending mechanism to sample and adapt to any pass element, resulting in consistent hotswap profiles without any programming.
