General Description
The MAX5904–MAX5909 dual hot-swap controllers provide complete protection for dual-supply systems. These devices hot swap two supplies ranging from +1V to +13.2V, provided one supply is at or above 2.7V, allowing the safe insertion and removal of circuit cards into live backplanes.

FEATUREs
♦ Safe Hot-Swap for +1V to +13.2V Power Supplies Requires One Input ≥ 2.7V
♦ Low 25mV Default Current-Limit Threshold
♦ Inrush Current Regulated at Startup
♦ Circuit Breaker Function
♦ Adjustable Circuit Breaker/Current-Limit Threshold
♦ VariableSpeed/BiLevel Circuit-Breaker Response
♦ Autoretry or Latched Fault Management
♦ On/Off Sequence Programming
♦ Status Output Indicates Fault/Safe Condition
♦ Output Undervoltage and Overvoltage Monitoring and/or Protection
