Special Features:

Allows safe board insertion and removal from a live, compactpci (tm) bus; controls 3.3v and/or 5v supplies; programmable foldback current limit during power-up; dual level circuit breakers protect supplies from overcurrent and short-circuit faults; local pci rst number logic on-chip; precharge output biases i/o pins during card insertion and extraction; user programmable supply voltage power-up rate; 15v high side drive for external n-channel mosfets; pwrgd, resetout and fault outputs; applications include compactpci bus removeable boards. The ltc1646 is availbable in the 16-pin narrow ssop package.

Properties:

An item specifically designed to absorb and consume surges of voltage such as that resulting across contacts when breaking a circuit having an inductive load or a burst of static across a telephone receiver. It is connected in parallel with the item it is protecting. It may be made up of metallic rectifier cells or semiconductor devices connected back-to-back which may or may not be shunted by a capacitor. It may also be a single rectifier cell or semiconductor device shunted by a capacitor. Excludes metallic rectifiers which are rated for rectifying capabilities and all single unit semiconductor devices not shunted by a capacitor. For items perfoming this function by use of voltage sensitive resistors, see resistor, voltage sensitive. See also cutout disk, protective.
