Supertex inc. HV101 3-Pin Hotswap, Inrush Current Limiter Controllers (Negative Supply Rail) Features General Description Pass element is only external part The HV101 is a 3-pin hotswap controller available in the SOT- 223 package, which requires no external components other No sense resistor required than a pass element. The HV101 contains many of the features Auto-adapt to pass element found in hotswap controllers with 8 pins or more, and which Short circuit protection generally require many external components. These features UV & POR supervisory circuits include undervoltage (UV) detection circuits, power on reset (POR) supervisory circuits, inrush current limiting, short cir- 2.5s auto retry cuit protection, and auto-retry. In addition, the HV101 uses a 10V to 72V input voltage range patent pending mechanism to sample and adapt to any pass 0.6mA typical operating supply current element, resulting in consistent hotswap profiles without any Built in clamp for AC path turn-on glitch programming.
