LTC1647-1/

LTC1647-2/LTC1647-3

Dual Hot Swap Controllers

FEATURES

DESCRIPTION

The LTC^®1647-1/LTC1647-2/LTC1647-3 are dual Hot

Swap™controllersthatpermitaboardtobesafelyinserted

and removed from a live backplane.

Allows Safe Board Insertion and Removal from a

Live Backplane

Programmable Electronic Circuit Breaker

FAULT Output Indication

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.

APPLICATIONS

The LTC1647-1 is a dual Hot Swap controller with a

Hot Board Insertion

common V pin, separate ON pins and is available in an

Electronic Circuit Breaker

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
