LTC4210-3 - Hot Swap Controller

General Description

The LTC®4210-3/LTC4210-4 is a 6-pin SOT-23 Hot Swap controller that allows a board to be safely inserted and removed from a live backplane.

An internal high side switch driver controls the GATE of an external N-channel MOSFET for a supply voltage ranging from 2.7V to 7V.

Key Features

  • nn Allows Safe Board Insertion and Removal from a Live Backplane nn Adjustable Analog Current Limit with Circuit Breaker nn Fast Response Limits Peak Fault Current nn Automatic Retry or Latch Off On Current Fault nn Adjustable Supply Voltage Power-Up Rate nn High Side Drive for External MOSFET Switch nn Controls Supply Voltages from 2.7V to 7V nn Undervoltage Lockout nn Adjustable Overvoltage Protection nn Low Profile (1mm) SOT-23 (ThinSOT™) Package.
