Catalyst Semiconductor Introduces 10-Bit Serial Latched LED Driver.SUNNYVALE, Calif. -- Catalyst Semiconductor, Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :CATS), a leading supplier of high performance analog/mixed-signal solutions and nonvolatile memory, today expanded its family of solid state illumination products with the introduction of a new white LED driver targeted at LED indicator and interior lighting applications. The CAT310 drives up to 10 color, or white, LEDs and safely handles "load dump" transients to 40V, making it ideal for automotive systems. A serial to parallel shift register accepts up to a 10-bit data stream, stores the state condition of each output channel, and upon command, latches the input data to enable, or disable, the outputs. This provides LED blanking and pattern control for signal indication in applications such as diagnostic tools or control panels. A serial output allows the user to cascade multiple CAT310 drivers to illuminate systems of LEDs in applications such as sign boards or interior lighting systems. Each channel is comprised of a low on-resistance open drain 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 which can sink up to 50mA, with the current through each LED being set by a series resistor. Manufactured on high-voltage CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology, the CAT310 operates with input voltages as high as 17V. Over voltage detection, under voltage lockout lockout, intentional closing up of a company, factory, or shop by an employer to prevent employees from working during a strike or labor dispute. The term lockout and over current detection each serve to protect the device and output LEDs during fault conditions. "The CAT310 offers a robust solution for driving multi-color LEDs across the full automotive temperature range in harsh system environments. The integrated suite of features reduces external component count and minimizes the traditional reliance on upstream protection devices, simplifying the overall system design," said Jamie White, Senior Marketing Manager. Product Features --Output drivers withstand load-dump transients up to 40V --Operates over automotive temperature range: -40 degrees to +125 degrees C --Drives 10 LEDs in parallel at 50mA per channel --Output channels can drive a combination of white or color LEDs --Serial output allows cascading of multiple CAT310's to drive greater than 10 LEDs --Operating voltage up to 17V --Simple LED pattern programming through the 10 MHz (MegaHertZ) One million cycles per second.
