IXHQ100PI

The IXHQ100PI shunt regulator ensures a wide operating voltage range (with the external MOSFET breakdown voltage as limit)which is a live insertion and removal hot swap controller with a built-in power noise filter. The IXHQ100PI incorporates 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 allows continuous load current rise adjustments, presettable maximum current limits, and user selectable fault indication turn off times for resetting Ps and other synchronous board level systems. For added flexibility, GSNSin pin is available to implement either circuit board insertion/removal detection or ground detection.The active power filter reduces power source output impedance, producing "clean" load power.

The features of IXHQ100PI can be summarized as (1)live insertion and removal power manager; (2)adjustable power-on slew rate; (3)autodetect of load open circuit or -VIN disconnection; (4)controlled time-delay; (5)operates from -9 to external MOSFET voltage limit; (6)fault indication output (microprocessor reset); (7)board insertionl removal detector input; (8)protection during turn-on; (9)low frequency power active filter; (10)adjustable electronic circuit Breaker; (11)Vin undervoltage with CSNSin input.
