Micrel
MIC2584/MIC2585
Dual-Channel Hot Swap Controller/Sequencer
General Description
The MIC2584 and MIC2585 are dual-channel positive volt-
age hot swap controllers designed to facilitate the safe
insertion of boards into live system backplanes. The MIC2584
and MIC2585 are available in 16-pin and 24-pin TSSOP
packages, respectively. Using a few external discrete com-
ponents and by controlling the gate drives of external N-
Channel MOSFET devices, the MIC2584/85 provides inrush
current limiting and output voltage slew rate control in harsh,
critical power supply environments. Additionally, the MIC2585
provides output turn-on sequencing and output tracking
during turn-on and turn-off. In combination, the devices’
many features provide a simplified, robust solution for many
network applications to meet the power sequencing and
protection requirements of multiple-voltage logic systems.
Features
• 1.0V to 13.2V supply voltage operation
• Surge voltage protection up to 20V
• Current regulation limits inrush current regardless of
load capacitance
• Programmable inrush current limiting
• Electronic circuit breaker
• Dual-level overcurrent fault sensing eliminates false
tripping
• Fast response to short circuit conditions (< 1µs)
• Two sequenced output mode selections
