Description

General part information

LTC1647 Series

The LTC1647-1/LTC1647-2/LTC1647-3 are dual Hot Swap™controllers that permit a board to be safely inserted and removed from a live backplane.Using external N-channel MOSFETs, the board supply voltages can be ramped up at a programmable rate. A high side switch driver controls the MOSFET gates for supply voltages ranging from 2.7V to 16.5V. A programmable electronic circuit breaker protects against overloads and shorts. The ON pins are used to control board power or clear a fault.The LTC1647-1 is a dual Hot Swap controller with a common VCCpin, separate ON pins and is available in an SO-8 package. The LTC1647-2 is similar to the LTC1647-1 but combines a fault status flag with automatic retry at the ON pins and is also available in the SO-8 package. The LTC1647-3 has individual VCCpins, ON pins andFAULTstatus pins for each channel and is available in a 16-lead narrow SSOP package.ApplicationsHot Board InsertionElectronic Circuit BreakerPortable Computer Device BaysHot Plug Disk Drive
