Description

General part information

LTC1643A Series

The LTC1643A is a Hot Swap™controller that allows a board to be safely inserted and removed from a live PCI-Bus slot. Two external N-channel transistors control the 3.3V and 5V supplies while on-chip switches control the –12V and 12V supplies. All supply voltages can be ramped up at a programmable rate. An electronic circuit breaker protects all four supplies against overcurrent faults. The foldback current limit feature limits current spikes and power dissipation when shorts occur and allows boards with large capacitances to be powered up without tripping the circuit breaker. ThePWRGDoutput indicates when all of the supply voltages are within tolerance and theFAULToutput indicates an overcurrent condition. The ON(LTC1643AH)/ON(LTC1643AL/ LTC1643AL-1) pin is used to cycle the board power or reset the circuit breaker. The LTC1643AL-1 has the ±12V power good comparators disabled.The LTC1643A is available in a 16-pin narrow SSOP package.ApplicationsPCI-Based ServersCompactPCI Compliant Boards
