Product Details

DESCRIPTION

The LTCÂ®4221 is a 2-channel Hot SwapTM controller that allows a board to be safely inserted and removed from a live backplane. Using two independent high side gate drivers to control two external N-channel pass transistors, the output voltages can be ramped up with current foldback to limit the inrush current during the start-up period. No external compensation capacitors are required at the GATE pins. The two channels can be configured to ramp up and down separately or simultaneously for supply voltages ranging from 2.7V to 13.5V and 1V to 13.5V for channels 1 and 2 respectively.

FEATURES

â– Allows Safe Board Insertion and Removal from a Live Backplane
â– Configurable Power Supply Sequencing
â– Soft-Start with Current Foldback Limits Inrush Current
â– No External Gate Capacitor Required
â– Adjustable Dual Level Circuit Breaker Protection
â– Controls Supply Voltages from 1V to 13.5V
â– Independent N-Channel MOSFET High Side Drivers
â– FB Pin Monitors VOUT for Overvoltage Protection
â– Latch Off or Automatic Retry on Current Fault
â– FAULT and PWRGD Outputs
â– Narrow 16-Pin SSOP Package

APPLICATIONS

â– Electronic Circuit Breaker
â– Power Supply Sequencing
â– Live Board Insertion and Removal
â– Industrial High Side Switch/Circuit Breaker
