Intersil first to deliver dual hot plug power controller for new PCI Express bus.Intersil Corporation (Nasdaq:ISIL ISIL International Society for Individual Liberty ISIL Interim Support Items List ISIL Intelligence Systems Integration Laboratory (Ft. Huachuca, Arizona; US Army facility for integrating intelligence systems) ), a leader in the design and manufacture of high performance analog and wireless networking See wireless network. solutions, has announced the industry's first dual-rail hot-swap controller targeted primarily for the new PCI Express bus. The new Endura ISL ISL - Interface Specification Language. Xerox PARC. Interface description language used by the ILU (Inter-Language Unification) system. Includes descriptions of multiple inheritance, exceptions and garbage collection. E-mail: Bill Janssen <janssen@parc.xerox.com>. 6161 allows boards to be safely inserted and removed from live backplanes. This new IC controls both 12-V and 3.3-V power buses, offering programmability and fast-response protection. In addition to PCI Express, the ISL6161 is also well suited for general power distribution control and other Hot-Swap and Hot Plug applications. The ISL6161 dual-rail controller offers a rich feature set that includes: under-voltage monitoring and "power good" notification, programmable over-current detection and fault isolation, programmable current regulation, programmable current limit time to latch off, adjustable turn on ramp for soft-start and fast one-microsecond response to a dead short. This dual controller offers customers a high degree of integration that results in savings in board space and balance of materials costs. Complete reference designs and evaluation boards are available. The ISL6161 provides Intersil's IntelliTrip dual-level current limiting technology for precise current control and protection. For over-current (OC) protection, the voltage across either sense resistor is monitored and compared to its user-programmed current-regulation (CR) voltage threshold value. When the voltage exceeds the CR threshold, the controller enters the current regulation mode, holding the current at the programmed level until either the OC event passes, in which case the MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged is again fully enhanced and the C(TIM TIM Timothy TIM Technical Interchange Meeting TIM Transient Intermodulation Distortion TIM Time Is Money TIM The Invisible Man (movie) TIM Telecom Italia Mobile (Italian cellular provider) ) capacitor is discharged, or the programmed time out period expires, in which case both the FETs are latched off. The IC responds to a severe OC load (greater than 3X programmed current limit) by turning off the FET FET: see transistor. (Field Effect Transistor) One of two major categories of transistor; the other is bipolar. FETs use a gate element that, when charged, creates an electromagnetic field that changes the conductivity of a silicon in less than 1 us. The controller is reset on the rising edge on the ENABLE-BAR pin and is turned on by the ENABLE-BAR pin being driven low. The ISL6161 is available now. The price, based on one thousand piece quantities, for the ISL6161CB in the 14-lead SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. package is $2.70 each. |
