EMA Adds Future Electronics Part Database Interface to Their Component Data Management Solution

Rochester, NY (June 22, 2010) – EMA Design Automation™ (www.ema-eda.com), a full-service provider of electrical and mechanical CAD tools, today announced the addition of Future Electronics to the list of component distributors included in the new 4.0 version of Component Information Portal (CIP), EMA’s component data management solution which provides design teams an automated method to manage their electronic part data. CIP is tightly integrated with Cadence® OrCAD® Capture CIS providing access to component distributor data directly within the OrCAD design environment, improving both data accuracy and operating efficiency.

“Since its initial release in July of 2008, customer adoption of CIP continues to increase because customers see real value in an out-of-the-box data management solution,” said Manny Marcano, president and CEO of EMA Design Automation. “With CIP, engineers are able to benefit from all the advantages that come with a centralized part library without having to become bogged down with designing and implementing a component database from scratch.”

CIP 4.0 adds the ability to search parametric data from the Future Electronics part catalog to its existing list of supported distributors, Digi-Key, Newark, and Premier Farnell. Users have online access to these part distributor databases allowing them to easily find available parts that meet their performance and financial requirements directly from their engineering desktop. With CIP 4.0, users can extend their part search across multiple distributors simultaneously to see which vendor best meets their needs. Once the desired part is found, CIP enables automatic download of the selected device parametric data directly into the component database; saving time and avoiding data entry errors that are common with manual methods. This data is then immediately available to design engineers directly within OrCAD Capture CIS. Since the parametric information has been collected from the part distributor this also provides purchasing with correct manufacturer and distributor part numbers, part costs, and available quantities to avoid component problems that can occur after the design is complete.

Going beyond distributor import functionality, CIP provides advanced component data management capabilities. Design teams can easily import external data into the component database, define user roles, and track database changes to keep everyone in synch as the design progresses. With CIP, users are provided with an automated methodology to implement, populate, and access their part data while ensuring consistency and proper design practices are being maintained. 

“The integration of our part numbers and inventory information with EMA CIP significantly improves the accuracy of the Bill of Materials (BOM) for our customers,” said Tom Galligani, Regional VP of Sales at Future Electronics. “This dramatically reduces the cost for both the customer and supplier when quoting, and provides the EMS partner with an accurate BOM for production. With the ever changing landscape of supply chains, these types of tools are essential to supply chain management needs.”

EMA also enables design teams to further extend data management to the corporate level by tying their engineering database into enterprise systems like ERP, MRP, and PLM using the Enterprise Link™ module. This integration gives teams the ability to access engineering and related corporate data together; all while remaining within the OrCAD Capture CIS environment. Utilizing the Enterprise Link module ensures that engineering can design with corporate requirements in mind and easily generate compliant BOMs that consist solely of parts that meet corporate standards. This capability is available as a separate option and can be purchased with or without CIP.

1.2A Overvoltage/Overcurrent Protector Isolates Sensitive Low Voltage Electronics from Input Power Surges

MILPITAS, CA – June 22, 2010 – Linear Technology Corporation introduces the LTC4362, a 2.5V to 5.5V overvoltage and overcurrent protector designed to safeguard low voltage, portable electronics from damaging input voltage transients and current surges. Overvoltage events can occur due to power adapter failure or faults, or when hot-plugging an AC adapter into a device’s power input. Inadvertently plugging the wrong power adapter into a device can potentially cause damage from overvoltage or negative supply voltage. The LTC4362 utilizes a 2% accurate 5.8V overvoltage threshold to detect an overvoltage event and responds quickly within 1µs (max) to isolate the downstream components from the input. Overvoltage protection of up to 28V is achieved with an internal, avalanche rated, low RDS(ON) MOSFET, and rides through inductive cable transients without requiring transient voltage suppressors (TVS) or other external components in most applications. In addition, the LTC4362 monitors the voltage drop across an internal current sense resistor to provide a 20% accurate, 1.5A overcurrent threshold. The LTC4362 is targeted for portable electronics with multiple power supply options, such as cell phones, MP3/MP4 players, digital cameras that charge via wall and car battery adapters and USB ports.

The LTC4362 controls an internal 40mOhm N-channel MOSFET so that under normal operation it provides a low loss path from the input to the load. Inrush current limiting is achieved with a controlled gate voltage slew rate. If the voltage at the input exceeds the overvoltage threshold of 5.8V, the GATE is pulled low within 1us to protect the load. The LTC4362 features a soft shutdown controlled by the /ON pin and provides a gate drive output for an optional external P-channel MOSFET for reverse voltage protection. A power good output pin indicates gate turn on. The LTC4362 is available in two options; the LTC4362-1 latches off after an overcurrent event, whereas the LTC4362-2 performs an auto-retry following a 130ms delay. Following an overvoltage condition, both options automatically restart with a start-up delay.

Specified over the full commercial and industrial temperature ranges, the LTC4362 is offered in 8-pin, 2mm x 3mm DFN packages. Evaluation boards and samples are available online. The LTC4362 is priced at $1.60 each in 1,000-piece quantities, and is available today in production. For more information, visit www.linear.com/pr/4362.
