Two families of charge-management controllers from Microchip feature Overvoltage Protection (OVP). The MCP73113, MCP73114 and MCP73213 Lithium-Ion (Li-Ion); and MCP73123, MCP73223 Lithium Iron Phosphate (LiFePO4) Chargers include voltage regulation and an integrated pass transistor.
Analysts have reason to believe that the long awaited Indian 3G spectrum auction may take place sooner rather than later, although its expected impact on competition and technology is thought to be vastly overstated.
NASA will test the powerful first stage of its new Ares moon rocket Thursday, a milestone in a program that has already spent $7 billion for a rocket that astronauts may never use. When that first stage is tested, it will be mounted horizontally. The engine will fire, shake and make lots of noise. But by design, it will not leave the ground. The same could be said for NASA's plans to go to the moon, Mars or beyond Earth orbit.
Rohm Semiconductor has introduced CMOS LDO regulators featuring the company’s proprietary automatic power-saving (APS) function that dynamically switches performance characteristics based on operating conditions. The BHxxPB1 Series combines
Combining a 2 percent constant on-time buck regulator and a 2 percent linear regulator, the A4402 regulator IC from Allegro provides dual output voltages (such as those required by microcontroller or DSP-based applications). The switching regulator includes an adjustable soft-start timer
Up to eight Model 6891 VME Boards (from Pentek) can be Linked, enabling it to handle clock rates up to 500 MHz. The VME board is intended for such applications as radar beamforming, direction finding and shipboard diversity reception, and cellular wireless applications.
The world’s leading mobile handset manufacturer, Finland’s Nokia, announced a move into financial services on Wednesday. The new direction for Nokia will see it working with mobile payment specialist Obopay, in which Nokia invested $70m in March this year.
Suitable for industrial and outdoor environments, the S Series of watertight toggle switches from NKK are rated to IP67 of IEC60529 Standards. Electrical capacities range from 15 A to 20 A at 125 VAC, 6 A to 10 A at 250 VAC and 15 A to 20 A at 30 VDC.
In its recently released , DisplaySearch forecasts that the total e-paper display market will grow to 1.8 billion units and $9.6 billion in revenues in 2018, from 22 million units and $431 million in revenues in 2009, for a CAGR (compound annual growth rate) of 41%for revenues and 64% for units.
Wikipedia, the online encyclopedia that has drawn some decidedly juvenile pranks, is looking to impose more discipline with new restrictions on the editing of articles. The latest changes come as Wikipedia tries to balance a need for credibility and a desire for openness. While anyone can still edit entries, the site is testing pages that won't register changes until they are approved by an experienced Wikipedia editor.
Internet criminals might be rethinking a favorite scam for stealing people's personal information. A report being released Wednesday by IBM Corp. shows a big drop in the volume of "phishing" e-mails, in which fraud artists send what looks like a legitimate message from a bank or some other company.
The CXLdp low pressure transducer from Ashcroft is available with jumper-selectable 0-5 vdc or 0-10 vdc outputs, as well as the original 4-20 mA output configuration. The CXLdp is available in bidirectional and unidirectional ranges from 0/0.1 through 0/25.0” H20 and in accuracies of ±0.8 percent and 0.4 percent FS.
Incorporating an integral sprocket or pulley, the RWT 350/360 TorqSense from Sensor Technology purportedly mounts in moments. For mounting in tight spaces, the RWT350/360 has its control electronics separate from the sensing head. The torque measuring system is intended for plants driven by a belt or chain drive.
With working temperature up to 105oC, the RL3-10 rocker switch series from Phaseda has 10 A 125 VAC UL approved rating. It comes in both single pole and double pole versions. The switch has On/Off function, On/Off/On, On/On, plus momentary spring return as well. The body is made from PA66, and contacts of silver alloy.
The UK is considering a law that would force ISPs to cut off service to those accused of illegally downloading movies and/or music. This has the potential to reignite an old debate—one that’s persisted since the term “digital media” was invented. Our handling of this issue has profound ramifications for the future of the entertainment industry.
