Description

The IXHQ100 is a live insertion and removal hot swap

controller with a built-in power noise filter. It incorpo-

rates all the active circuitry necessary to protect circuit

boards during live insertion or removal (insertion or

removal when the system power is active). Additionally,

the IXHQ100 incorporates two unique features: power

active filter for powerline noise suppression and power

auto-disconnect detector which eliminates the need of

additional staggered pins.

The IXHQ100 shunt regulator ensures a wide operating

voltage range (with the external MOSFET breakdown

voltage as limit). The active power filter reduces power

source output impedance, producing "clean" load

power. The IXHQ100 allows continuous load current

rise adjustments, presettable maximum current limits,

and user selectable fault indication turn off times for

resetting

µPs and other synchronous board level sys-

tems. For added flexibility, GSNSin pin is available to

implement either circuit board insertion/removal detec-

tion or ground detection.
