LTC4226
Overview
The LTC®4226 dual Hot Swap™ controller allows two power paths to be safely inserted and removed from a live backplane or powered connector. Using N-channel pass transistors, supply voltages ranging from 4.5V to 44V are ramped up at an adjustable rate.
- Allows Safe Board Insertion into Live Backplane
- Selectable Current Limit and Dual-Rate Timer Accommodate Load Surges
- Fast Response Limits Peak Fault Current
- Wide Operating Voltage Range: 4.5V to 44V
- Optional Auto-Retry or Latchoff after Overcurrent Fault
- High Side Drive for External N-Channel MOSFET
- Allows Parallel Power Paths for High Current
