Semtech SC4150

Negative-Voltage Hot-Swap Controller

Features


  • Programmable slew of the inrush current when used for hot insertion in the negative 24 V and 48 V backplane
  • Closed-loop operation limits the maximum current even in short-circuit condition
  • Built-in timer prevents false shutdown, when the closed-loop operation limits the current
  • Sensing the drain voltage allows for immediate shutdown in short-circuit condition, where current spikes and noise is ignored
  • Power-good signal
  • Input UVLO and OVLO sensing
  • SO-8 package

Applications


  • Central office switching
  • Negative 48 V distributed power systems
  • Power supply hotswap & inrush control

Packaging

SOIC-8
