Overview

The LTC®4282 hot swap controller allows a board to be safely inserted and removed from a live backplane. Using one or more external N-channel pass transistors, board supply voltage and inrush current are ramped up at an adjustable rate.

  • Allows Safe Board Insertion Into Live Backplane
  • 12-/16-Bit ADC with ±0.9% Total Unadjusted Error
  • Monitors Current, Voltage, Power and Energy
  • Controls Two Parallel N-Channel MOSFETs for SOA Sharing in High Current Applications
  • Internal EEPROM for Nonvolatile Configuration
  • Wide Operating Voltage Range: 2.9V to 33V
  • I2C/SMBus Digital Interface (Coexists with PMBus Devices)
  • 12V Gate Drive for Lower MOSFET RDS(ON)
  • Programmable Current Limit with 2% Accuracy
  • MOSFET Power Limiting with Current Foldback
