LTC4260 - Positive High Voltage Hot Swap Controller

Description

The LTC®4260 Hot Swap™ controller allows a board to be safely inserted and removed from a live backplane.

Using an external N-channel pass transistor, the board supply voltage can be ramped up at an adjustable rate.

Features

  • n Allows Safe Board Insertion into Live Backplane n 8-Bit ADC Monitors Current and Voltage n I2C™/SMBus Interface n Wide Operating Voltage Range: 8.5V to 80V n High Side Drive for External N-Channel MOSFET n Input Overvoltage/Undervoltage Protection n Optional Latchoff or Autoretry After Faults n Alerts Host After Faults n Foldback Current Limiting n Available in 24-Lead SO, 24-Lead Narrow SSOP and 32-Lead (5mm × 5mm) QFN Packages.
