Product Overview

The LTC1645CS8#PBF is a 2-channel Hot Swap Controller allows a board to be safely inserted and removed from a live backplane. 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 1.2 to 12V. The two channels can be set to ramp up and down separately, or they can be programmed to rise and fall simultaneously, ensuring power supply tracking at the two outputs. Programmable electronic 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 user-programmed voltage. An additional spare comparator is available for monitoring a second supply voltage.
