MIC2586/MIC2586R
Single-Channel, Positive High-Voltage
Hot Swap Controller/Sequencer
NOT RECOMMENDED FOR NEW DESIGNS
General Description
The MIC2586 and MIC2586R are single-channel positive
voltage hot swap controllers/sequencers designed to
provide safe insertion and removal of boards for systems
that require live (always-powered) backplanes. These
devices use few external components and act as
controllers for external N-channel power MOSFET devices
to provide inrush current control and output voltage slew
rate control. Overcurrent fault protection is provided via
programmable analog foldback current-limit circuitry
equipped with a programmable overcurrent filter. These
protection circuits combine to limit the power dissipation of
the external MOSFET to insure that the MOSFET is in its
SOA during fault conditions.
The MIC2586 provides a circuit breaker function that
latches the output MOSFET off if the load current exceeds
the current-limit threshold for the duration of the
programmable timer. Conversely, the MIC2586R will
attempt to restart power after a load current fault with a low
duty cycle to prevent the MOSFET from overheating.
Each device provides either an active-HIGH (−1BM) or an
active-LOW (−2BM) “power-is-good” (PWRGD) signal.
The MIC2586 and the MIC2586R provide up to three,
time-sequenced PWRGD outputs that can be used as a
control for DC/DC converter circuits or power modules.
