General Description
The HV101 is a 3-pin hotswap controller available in the SOT-
223 package, which requires no external components other
than a pass element. The HV101 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 cir-
cuit protection, and auto-retry. In addition, the HV101 uses a
patent pending mechanism to sample and adapt to any pass
element, resulting in consistent hotswap profiles without any
programming.
