HV300 - Inrush Current Limiter Controllers

Datasheet Summary

Description

The Supertex HV300, Hotswap Controller, Negative Supply controls the power supply connection during insertion of cards or modules into live backplanes.

It may be used in traditional ‘negative 48V’ powered systems or for higher voltage busses up to negative 90V.

Features

  • PWRGD = Active HIGH.
  • -10V to -90V input voltage range.
  • Few external components.
  • 0.33mA typical standby supply current.
  • Programmable over/under voltage limits with hysteresis.
  • Programmable current limit.
  • Active control during all phases of start-up.
  • Programmable timing.
  • 8-Lead SOIC package.
