MIC2596/2597
Dual Channel Negative Voltage Hot Swap Controllers
Advance Information
General Description
The MIC2596 and MIC2597 are dual channel negative volt-
age hot swap controllers designed to facilitate safe PC board
insertion into and removal from live backplanes. To minimize
external components, each channel of the MIC2596/MIC2597
has an integrated high voltage power MOSFET. Built-in
current sensing in each channel provides inrush current
limiting, by regulating the channel’s output current to a user-
settable maximum. Current sensing also provides program-
mable overcurrent and open-load detection. A channel will
be turned off if it experiences overload or no-load conditions
lasting longer than programmable intervals. Foldback cur-
rent limiting holds power dissipation of the internal MOSFETs
at safe levels during overloads, and very fast shutdown
response to faults ensures protection for both system power
supplies and the load. The MIC2596 will automatically
attempt to restart into an overcurrent fault until the fault is
cleared, while the MIC2597 will latch the output in the off state
until it is reset by external action. A logic-compatible signal
is provided on each channel to indicate overcurrent or under-
current fault conditions.
