Revision 2.0
General Description
The MIC2587 and MIC2587R are single-channel positive
voltage hot swap controllers 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 fold-
back current-limit circuitry equipped with a programmable
overcurrent filter. These protection circuits combine to limit
the power dissipation of the external MOSFET to ensure
that the MOSFET is in its SOA during fault conditions. The
MIC2587 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. The MIC2587R provides a circuit breaker function
that automatically attempts to restart power after a load
current fault at a low duty cycle to prevent the MOSFET
from overheating. Each device provides either an active-
HIGH (1YM) or an active-LOW (2YM) Power-is-Good
signal to indicate that the output load voltage is within
tolerance of the application circuits design objective.
