Single Channel Hot Swap Controller
Preliminary Information
General Description
The MIC2582 and MIC2583 are single channel positive
voltage hot-swap controllers designed to allow the safe
insertion of boards into live system backplanes. Using few
external components, the parts act in conjunction with an
external N-Channel MOSFET device, for which the gate drive
is controlled to provide inrush current-limiting and output
voltage slew rate control. The MIC2582/3 are rated for
operation from supply voltages from 2.3V to 13.2V, but can
withstand transient voltages as high as 20V without damage.
Overcurrent fault protection is provided along with a program-
mable over-current threshold. Active current regulation dur-
ing start-up ensures that inrush current never exceeds the
programmed threshold. The MIC2582/3 provide a circuit
breaker function that latches the output MOSFET off if the
current limit threshold is exceeded for a programmed period
of time. Dual-level fault detection allows very fast response
to short-circuit faults while preventing lower level overcurrent
transients from causing “nuisance tripping” of the circuit
breaker. A /FAULT signal is provided indicating overcurrent
or undervoltage fault conditions.
Features
• Provides safe insertion and removal from live
backplanes
• 2.3V to 13V supply voltage operation
• Surge voltage protection up to 20V
• Undervoltage Lockout protection
• Programmable inrush current-limiting
• Current regulation limits inrush current regardless of
load capacitance
• Dual-level overcurrent fault sensing eliminates false
tripping
• Fast response to short circuit conditions (< 1
µs)
• Power-On Reset and Power-Good status outputs
(MIC2583)
• Programmable output undervoltage detection
• Electronic circuit breaker
• /FAULT status output
• Auto-restart function (MIC2583R)
