Intersil's New 4-Channel Supervisory IC Fills Market Gap with Easy Programmability and Accuracy Along with Space and Cost Savings.Business Editors/High-Tech Writers MILPITAS, Calif.--(BUSINESS WIRE)--Sept. 29, 2003 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 world leader in the design and manufacture of high performance analog solutions, today announced a new 4-channel voltage supervisory IC, the 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>. 6536. This space and cost saving Intersil Endura(TM) power IC fills a market gap left by legacy solutions for accurately monitoring and reporting on the status of multiple voltage rails. Four bus voltages can be accurately monitored with this single IC and a handful of resistors used to program voltage thresholds. This supervisory function is critical for reliable operation in many of today's applications such as: computing, communications, graphics, industrial, medical and instrumentation systems. Voltage supervision prevents power from being applied to CPUs, GPUs, DSPs, and ASICs before all supplies are present and stable. Otherwise, damage would occur to these sensitive and costly components. Legacy solutions have been far less integrated and more spread out across the board with a greater bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. and associated manufacturing costs. The ISL6536 eliminates this excess while offering simple programming and accuracy. Using an internal 0.63-V reference, the ISL6536 is able to provide accurate monitoring of four separate voltage buses at and above 0.7 V. Thresholds for each monitored voltage bus are set independently using a simple resistor voltage divider voltage divider: see potentiometer. . Virtually any voltage level can be monitored simply using a resistor divider, which drops the voltage to 0.63 V for comparison. Operation of the ISL6536 is straightforward. After the IC is properly powered and enabled and all four voltage monitor (VMON) inputs are satisfied, the power good (PGOOD) output will go high to signal that voltage is valid on all four rails. Subsequently when the monitored voltage on any rail drops below its user-defined threshold point, the PGOOD output goes low. Each rail's VMON point is independently adjustable with a simple resistor divider. The PGOOD output is guaranteed to be valid even with the IC's supply voltage as low as 1 V. Also, the PGOOD output is an open-drain to allow OR-ing of multiple supervisory ICs and interfacing to a range of logic levels. The ENABLE input provides for a reset of the PGOOD output when it is pulled down below 0.5 V. With an internal 10-uA pull-up to VDD See Vcc. , the ENABLE can be signaled using common logic or pulled to ground with a push button switch. The ISL6536 is also designed to ignore 30-us transients at the VMON inputs, which eliminates would-be glitching Glitching is the practice of finding and exploiting flaws in video games to achieve something that was not intended by the game designers*. Glitching became controversial when multiplayer gaming became popular and glitches were exploited to give players an advantage over other . ISL6536 Technical Summary -- 2.7 V to 4 V IC supply voltage -- 4 channels monitors 4 voltage buses, each 0.7 V or higher -- Independent resistor divider threshold setting for each channel -- Active high PGOOD signal with ENABLE reset -- PGOOD is open-drain to allow OR-ing and logic-level matching -- PGOOD remains valid until the IC supply (VDD) falls below 1 V -- VMON glitch A temporary or random hardware malfunction. It is possible that a bug in a program may cause the hardware to appear as if it had a glitch in it and vice versa. At times it can be extremely difficult to determine whether a problem lies within the hardware or the software. See glitch attack. immunity, ignores 30-us transients -- 0.63 V internal reference voltage -- 8-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, industrial temperature range ISL6536 Pricing and Availability The ISL6536IB (SOIC) is available now. The suggested resale price is $0.75 for each IC in 4999 to 9999 unit quantities.
