Hot Swap Controller Guards Boards

The LTC1645 is a 2-channel hot swap controller that allows boards to be safely inserted and removed from live backplanes. Using external n-channel pass transistors, the supply voltages can be ramped at a programmable rate. Two high-side switch drivers control the n-channel gates for supply voltages ranging from 1.2V to 12V. The two channels can be set to ramp up and down separately, or they can be programmed to rise and fall simultaneously to ensure power supply tracking at the two outputs. Programmable circuit breakers protect against shorts at either output. The RESET output can be used to generate a system reset when a supply voltage falls below a user-programmed voltage. An additional spare comparator is available to monitor a second supply voltage. The device is available in 8- and 14-pin SOPs.
