General Description
The HV100 is a 3-pin hotswap controller available in the SOT-223 package, which requires no external components other than a pass element.
The HV100 contains 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 uses a patent pending mechanism to sample and adapt to any pass element, resulting in consistent hotswap profles without any programming.
