The HV100 and the HV101 are 3-pin hotswap controllers available in the SOT-223 package, which require no external components other than a pass element. The HV100 and the 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 and the HV101 use a patent pending mechanism to sample and adapt to any pass element, resulting in consistent hotswap profi les without any programming.
