Output voltage clamping with hot swap IC

Keywords:LM5069? hot swap controller? Under-Voltage Lock Out?

According to National Semiconductor, one of the benefits of using the LM5069 hot swap controller, besides inrush current limiting and fault monitoring, is that the controller supplies a voltage to the load that is between defined limits. This feature prevents the load from receiving a voltage less than what it is rated for (which could result in erratic behavior), and prevents it from receiving a voltage higher than what it is rated for, which could result in overheating and/or damage. The voltage limits to the load are set by the Under-voltage Lock Out and Over- voltage Lock Out thresholds, which are set with external resistors.
