MIC2584/2585 Micrel MIC2584/MIC2585
Dual-Channel Hot Swap Controller/Sequencer General Description Features The MIC2584 and MIC2585 are dual-channel positive voltage 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 components and by controlling the gate drives of external NChannel 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. 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 (< 1Вµs) Two sequenced output mode selections
(MIC2585 only) ∆250mV supply tracking mode during turn-on/turn-off
(MIC2585 only) Overvoltage and undervoltage output monitoring
(Overvoltage for MIC2585 only) Undervoltage lockout protection /FAULT status output Power-On Reset and Power-Good status output
(Power-Good for MIC2585 only) Applications RAID systems
