Constant-Current LED Driver Allows Multiple Devices to Be Cascaded and Programmed Via One Serial InterfaceJanuary 21, 2008 5:13 am | Comments
Catalyst Semiconductor, Inc. has expanded its recently introduced family of large LED video display drivers with the CAT4008, an 8-channel, constant-current sink LED driver for billboard, marquee, instrument and other large, general-purpose LED displays. The device’s LED channels can operate with an output voltage on the LED pins as low as 0.4V (for 2mA to 100mA LED current), to enable more power-efficient designs.
Dytran Instruments Inc. introduced an ultra miniature IEPE accelerometer which is laser welded in a titanium housing. Weighing in at just 0.2 grams, this miniature accelerometer successfully reduces mass loading effects. Because of its tiny “teardrop” design, the 3224A2 is suitable for vibration measurements in small locations. The model 3224A2 is available with a sensitivity of 2mV/g and can operate at temperatures up to 300°F.
International Rectifier introduced the IRS26302D protected 600V three-phase gate driver IC with ground fault protection. The IC has a seventh gate drive channel for a power factor correction (PFC) switch or inverter brake, making it well-suited to medium power appliance motor control and many other general-purpose three-phase inverter applications. The controller integrates power MOSFET/IGBT gate drivers
Agilent Technologies Inc. introduced a family of coaxial solid-state PIN diode switches -- including the P9400A/C transfer, P9402A/C SPDT and P9404A/C SP4T switches -- with a broad operating frequency range from 100 MHz up to 18 GHz for fast, accurate test in automatic test equipment (ATE) systems. Desirable isolation and ultra-fast switching speed make these switches suited for R&D and manufacturing engineers designing manufacturing test systems or requiring a fast switching solution to validate component performance.
E-Switch announced its modular MDP-16 Series of illuminated pushbutton switches. Its modular interface design features an attractive front panel and many illumination options. Actuator styles include a low or high bezel, and a flush mount or full guard option. There are six actuator colors to choose from. Specifications include electrical life of 6,000 cycles both silver and gold; mechanical life of 50,000 cycles typical; contact rating is
CAO Group introduced a High Flux Dynasty LED bulb, designed with a driver included in the base to provide constant current, transforming AC/DC low voltage to ~3.3 V. Available with both white and color LEDs, the bulb is screw-mounted on a waterproof 1156 base. With these standard connection bases, it is possible to
CIT RELAY & SWITCH offers the LPH Series bi-color, lighted pushbutton switch with numerous new cap options. Available with DPDT or 4PDT switch function, this versatile switch offers both momentary and latching styles. The LED color options available are red, green, yellow and blue – simply choose one or two colors for your application. Design engineers can choose the switch without a cap, a clear cap in two sizes or a misty silver style with 10 laser etching options.

V-Infinity, a division of CUI Inc, introduced a series of high density, medically approved open frame switching power supplies. The VMS-160 series outputs 160W with 200 LFM forced air cooling or 100W under convection-cooled conditions. This translates to a power density of 18 W/in³ in a 1U, industry standard, 2” x 4” footprint. The power supplies are approved to both medical EN60601-1 and ITE EN60950-1 safety standards. This series delivers
Maxim Integrated Products introduced the MAX3624 and MAX3625 high-performance, quad/triple-output clock generators for network equipment. These devices use a low-noise VCO and PLL architecture to generate a high-frequency, ultra-low-jitter (0.36 psRMS) clock signal from a low-frequency crystal resonator or reference clock input. They help to reduce space requirements by only requiring an external
Ramtron International Corp.'s FM31x Processor Companion family now has a real-time clock requiring only a standard 12.5pF external watch crystal.
