LM5068 Datasheet Negative Voltage Hot Swap Controller

Manufacturer: Texas Instruments

Overview: LM5068 .ti. SNVS254C – JANUARY 2004 – REVISED MARCH 2013 LM5068 Negative Voltage Hot Swap Controller Check for Samples:.

General Description

The LM5068 hot-swap controller provides intelligent control of power supply connections during the insertion and removal of circuit cards powered by live system backplanes.

The LM5068 provides both in-rush current control and short-circuit protection functions, and limits power supply transients in the backplane caused by the insertion of additional circuit cards.

The LM5068 controls the external N-Channel MOSFET to provide programmable load current limiting and circuit breaker functions using a single external current sense resistor.

Key Features

  • 1.
  • 2 Safe Module Insertion and Removal from Live Backplanes.
  • In-Rush Current Limiting for Safe Board Insertion into Live Backplanes.
  • Fast Response to Over-Current Fault Conditions with Active Current Limiting.
  • -10V to -90V Input Range.
  • Programmable Under-Voltage/Over-Voltage Shutdown Protection with Adjustable Hysteresis.
  • Programmable Multi-Function Timer for Board Insertion De-Bounce Delay.
  • Fault Timer Avoids Nuisance Trips Caused by.
