General Description
The HV100/HV101 are 3-pin hotswap controllers available in
SOT-223 and MLP packages, which require no external compo-
nents 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 limit-
ing, 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.
The only difference between the HV100 and the HV101 is the
internally set undervoltage (UV) threshold.
