Quad DMOS Full-Bridge PWM Motor Driver

The A3988 quad DMOS full-bridge driver from Allegro MicroSystems (Worcester, MA) can drive two stepper motors or four DC motors. Each fullbridge output is rated to 1.2 A and 36 V. The A3988 includes fixed off-time pulse width modulation (PWM) current regulators; DC motors in forward, reverse, and coast modes; and 2-bit nonlinear DACs (digital-toanalog converters) that allow stepper motors to be controlled in full, half, and quarter steps. The PWM current regulator uses Allegro’s patented mixed decay mode for reduced audible motor noise, increased step accuracy, and reduced power dissipation.

Real-Time Controller Enables Embedded Graphical Design

National Instruments (NI, Austin, TX), in collaboration with Freescale Semiconductor and Wind River, has developed the NI cRIO-9012 real-time controller based on Freescale’s MPC5200 processor built on Power Architecture™ technology, and Wind River’s VxWorks realtime operating system (RTOS). Embedded graphical system design combines open software and commercial off-the-shelf (COTS) programmable hardware in one unifying platform to design, prototype, and deploy embedded systems. Freescale’s 400- MHz MPC5200 processor contains an integrated floating-point unit that is suited for networking, media, industrial control, and automotive applications. The MPC5200, which is programmed with NI’s LabVIEW Real-Time Module, gives the cRIO-9012 controller up to four times the processing performance. Running on the MPC5200, the Wind River VxWorks RTOS delivers a fault-tolerant file system that provides data-logging, allowing engineers to operate the controller for long periods of time in remote applications using a battery or solar power.

Pentium M-Based Slot-O Controller

KineticSystems (Lockport, IL) has announced the V155, a VXI Slot-0 controller featuring a Pentium® M embedded processor. The V155 is a single- width C-size module with 1.1-GHz, 1.6-GHz, and 1.8-GHz clocking options. It features dual Ethernet controllers that support 10BaseT, 100BaseTX, and 1000BaseT interfaces; 2 GBytes of bootable flash on a secondary IDE; 1.5 GByte of PC1600 DDR SDRAM; and one PMC expansion site for user expandability for FDDI, CompactFlash, GPIB, Fibre Channel, or FPDP. The V155 also supports the VXI Plug & Play Virtual Instruments Systems Architecture (VISA) Library, which allows modules to be controlled via several interfaces with the same I/O function calls. Industry-standard VISA support allows the V155 to be integrated into existing systems, while dual Ethernet ports enable direct LAN access for connectivity with LXI-based systems. The controller is suitable for data acquisition and control for applications such as ATE, and aerospace and aircraft testing.

Platform Enables Wideband Data Links and SATCOM Processing

Mercury Computer Systems (Chelmsford, MA) has announced its integrated COTS application-ready platform for wideband data links and satellite communications (WBDLS) processing. The suite includes the Mercury Echotek™ Series ECV4-RFT 6U Wideband Remote Fiber Transceiver, which combines A/D and D/A technology, Xilinx® Virtex™-4 FPGA reconfigurable processing, and fiber I/O. The board brings COTS to applications such as 274- Mbps and wideband data links that require a blend of wideband I/O from dual 1.5-Gsps 8-bit A/D converters and dual 1.2-Gsps 14-bit D/A converters. The onboard FPGA reconfigurable processing resources enable multi-board coherent processing in distributed systems.

Single-Port Power Over Ethernet Controller Enables PSE Design

Linear Technology Corp. (Milpitas, CA) has introduced the LTC4263, an autonomous single-channel Power Sourcing Equipment (PSE) controller with an onboard MOSFET for use in IEEE 802.3af Power Over Ethernet (PoE)-compliant systems. The IC functions as a single-port PSE tool that detects, classifies, and provides isolated 48V power to Powered Devices (PDs) connected to it. Offering standard-compliant AC or DC methods to sense the removal of a PD and featuring onboard control algorithms, the LTC4263 provides autonomous operation through required tasks without processor intervention. Using an internal sense resistor, the LTC4263 provides inrush, and current limit and short-circuit control to ensure IEEE 802.3af compatibility.

10-Port Industrial Ethernet Managed Switch Supports Networking Features

SIXNET (Clifton Park, NY) has introduced the ET-10MG, a 10-port industrial Ethernet managed switch offering eight 10/100 Mbps RJ45 ports plus two Gigabit combination ports for copper or fiber connections. All of the RJ45 copper ports support auto-negotiating (10/100 or 10/100/1000), auto-crossover, and auto-polarity for plug-and-play connections. The fiber ports 9 and 10 also accept SFP fiber-optic transceivers for noise-immune links up to 80 km.
