MIC2588/MIC2594
Single-Channel, Negative High-Voltage Hot
Swap Power Controllers
General Description
The MIC2588 and the MIC2594 are single-channel, nega-
tive-voltage hot swap controllers designed to address the
need for safe insertion and removal of circuit boards into
live high-voltage system backplanes, while using very few
external components. The MIC2588 and the MIC2594 are
each available in an 8-pin SOIC package and work in con-
junction with an external N-Channel MOSFET for which the
gate drive is controlled to provide inrush current limiting and
output voltage slew-rate control. Overcurrent fault protection
is also provided and includes a programmable overcurrent
threshold. During an output overload condition, a constant-
current regulation loop is engaged to ensure that the system
power supply maintains regulation. If a fault condition exceeds
a built-in 400祍 nuisance-trip delay, the MIC2588 and the
MIC2594 will latch the circuit breakers output off and will
remain in the off state until reset by cycling either the UV/OFF
pin or the power to the IC. A master Power-Good signal is
provided to indicate that the output voltage of the soft-start
circuit is within its valid output range. This signal can be used
to enable one or more DC-DC converter modules.
