Abstract
A surge suppression circuit for gradually charging a capacitance of a device being hot plugged into a system, such as a disk drive being hot plugged into a RAID system. Without reliance on a permanently turned-on series element, such as a pass transistor, the surge suppression circuit uses a trigger circuit in combination with either a current limiting circuit or a slew rate control circuit. The current limiting circuit relies on a current sensing resistor in combination with a transistor that turns on when a voltage reaches a certain level across the current sensing resistor. The slew rate control circuit relies on a feedback mechanism that includes a capacitor and a resistor for maintaining a substantially constant rate of charging the capacitance of the device being hot plugged.
