MIC2589/MIC2595
Single-Channel, Negative High-Voltage Hot
Swap Power Controller/Sequencer
General Description
The MIC2589 and MIC2595 are single-channel,
negative voltage hot swap controllers designed to
address the need for safe insertion and removal of
circuit boards into “live” system backplanes, while using
few external components. The MIC2589/MIC2589R and
the MIC2595/MIC2595R are each available in 14-pin
SOIC packaging and work in conjunction 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 via a programmable overcurrent threshold
and filter. Very fast fault response is provided to ensure
that system power supplies maintain regulation even
during output short circuits. These controllers offer two
responses to a circuit breaker fault condition: the
MIC2589 and MIC2595 latch the circuit breaker’s output
off when the overcurrent threshold interval is exceeded
and the overcurrent filter times out while the MIC2589R
and MIC2595R automatically attempt to restart at a fixed
duty cycle after a current limit fault. A primary Power-
Good signal and two secondary (delayed and
staggered) Power-Good signals are provided to indicate
that the output voltage is within its valid operating range.
These signals can be used to perform an all-at-once or
a sequenced enabling of one or more DC-DC power
modules.
All support documentation can be found on Micrel’s web
site at www.micrel.com.
