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 undervolt-
age (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, result-
ing in consistent hotswap profiles without any programming.
