HV101 Datasheet | Supertex Inc

Features - - Pass element is only external part - - No sense resistor required - - Auto-adapt to pass element - - Short circuit protection - - UV & POR supervisory circuits - - 2.5s auto retry - - ±10V to ±72V input voltage range - - 0.6m A typical operating supply current - - Built in clamp for AC path turn-on glitch General Description The HV101 is a 3-pin hotswap controller available in the SOT223 package, which requires no external ponents 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 ponents. 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 HV101 uses a patent pending mechanism to sample and adapt to any pass element, resulting in consistent hotswap profiles without any programming.
