1 / 24 page  1 LTC1645 Dual-Channel Hot Swap Controller/Power Sequencer The LTC ®1645 is a 2-channel Hot SwapTM controller that 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 1.2V to 12V. The two channels can be set to ramp up and down separately, or they can be programmed to rise and fall simultaneously, 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 a user-programmed voltage. An additional spare com- parator is available for monitoring a second supply voltage. The LTC1645 is available in the 8- and 14-pin SO packages. s Hot Board Insertion s Power Supply Sequencing s Electronic Circuit Breaker s Allows Safe Board Insertion and Removal from a Live Backplane s Programmable Power Supply Sequencing s Programmable Electronic Circuit Breaker s User-Programmable Supply Voltage Power-Up and Power-Down Rate s High Side Drivers for External N-Channel FETs s Controls Supply Voltages from 1.2V to 12V s Ensures Proper Power-Up Behavior s Undervoltage Lockout s Glitch Filter Protects Against Spurious RESET Signals , LTC and LT are registered trademarks of Linear Technology Corporation.
