Turnkey Energy-Harvesting Reference Design

http://eon.businesswire.com/news/eon/20110616006103/en/Arrow-Electronics-Offers-Turnkey-Energy-Harvesting-Reference-Design

Teams with industry-leading suppliers to provide comprehensive, self-sustaining, ultra-low-power wireless sensor network solution

June 16, 2011 10:24 AM Eastern Daylight Time 

MELVILLE, N.Y.–(EON: Enhanced Online News)–Arrow Electronics, Inc. has joined with leading suppliers Silicon Labs, Infinite Power Solutions and Linear Technology Corporation to launch a turnkey energy-harvesting reference design enabling wireless networks powered by a solar energy-harvesting source.

“Working together with industry leaders Silicon Labs, Infinite Power Solutions and Linear Technology, we’ve developed a complete solution that can help customers reduce the complexity and enhance the sustainability of a variety of wireless networking applications”

The energy-harvesting reference design offers a simple, cost-effective bill of materials based on several key components. The design includes a solar-powered wireless sensor node that measures temperature, light level and charge level. It uses Silicon Labs’ ultra-low-power Si10xx wireless microcontroller (MCU) to control the sensor system and transmit data wirelessly. It also incorporates a thin-film battery to store harvested energy, as well as a battery charger IC for efficient power management. The data is transmitted to a wireless USB adapter included with the reference design that connects the wireless sensor node to a PC where sensor data for up to four nodes is displayed via an easy-to-use network GUI.

“Working together with industry leaders Silicon Labs, Infinite Power Solutions and Linear Technology, we’ve developed a complete solution that can help customers reduce the complexity and enhance the sustainability of a variety of wireless networking applications,” said David West, vice president of supplier marketing and asset for Arrow Electronics.

Silicon Labs’ Si10xx wireless MCUs offer very low active current of 160 µA/MHz and very low sleep mode current, as low as 25 nA, to conserve system resources. The Si10xx MCUs can also wake up very quickly in 2 µS. An on-chip wireless transceiver enables 20 dBm output power and RF sensitivity of -121 dBm, greatly increasing the wireless range. An integrated dc-dc switching regulator enables a wide input voltage range of 0.9V to 3.6V, which is particularly useful in energy-harvesting applications where outputs typically vary.

The reference design uses a THINERGY® solid-state, rechargeable, micro-energy cell (MEC), a unique type of thin film battery, with a capacity of 0.7 mAh developed by Infinite Power Solutions. In direct sunlight, the battery can be recharged fully in only one hour. While in sleep mode, the wireless sensor node will retain a charge for 7,000 hours. If the wireless system is transmitting continuously, it will operate non-stop for about three hours, although it is designed to constantly recharge itself at an appropriate level to keep the MEC from completely discharging.

Linear’s LTC4071 battery charger IC provides additional power management and offers an easy-to-use shunt battery system for Li-ion/Polymer batteries that integrates a charger and battery pack protection into one IC.

The LTC4071, with its 550 nA operating current, charges and protects batteries from previously unusable very low current, intermittent or continuous charging sources.

The LTC4071 can charge at currents up to 50 mA. A near zero (0.1 nA ) low-battery-latching disconnect function protects even low-capacity batteries from deep discharge and potentially irreparable damage. With pin-selectable settings of 4.0 V, 4.1 V or 4.2V, the LTC4071 IC’s 1 percent accurate battery float voltage allows the developer to optimize the balance between battery capacity and lifetime.

Silicon Labs’ wireless sensor energy-harvesting reference design accommodates a wide range of harvested energy sources. An on-board bypass connector gives developers the flexibility to tap other energy-harvesting sources such as vibration, thermal and RF.

LED System Design: You Get What You Pay For

LED System Design:

You Get What You Pay For

Werner MashigWerner Mashig, Arrow

LED lighting can clearly have advantages over traditional lighting technologies.

LEDs can have a long lifespan (>50k hours), use less energy, and provide more flexibility in a lighting design.

However, a poorly designed system, or making too many compromises on cost, can cause LEDs to underperform relative to expectations.

When designing, the process all starts with the LED selection.

While there is a wide selection of manufacturers and LED types to choose from, most LEDs are designed for specific applications. These applications include, but are not limited to:

  • Portable (flashlights, medical headlamps, etc.)
  • Signage (full video, variable message, traffic lights, etc.)
  • Backlighting (TVs, handhelds, etc.)
  • Transportation (planes, trains, automobiles, etc.)
  • General lighting (luminaries and LED bulbs)

Furthermore, there are LEDs specifically designed for sub-segments of these applications. When selecting the LED for an application design, it is important to choose one that can perform within the appropriate lifespan, efficacy, color shift, uniformity, thermal, electrical, and optics expectations. The manufacturer should be able to support the customer’s expectations by providing the necessary data to prove an application’s quality. While it can be tempting to select the most cost-effective LED, designers need to be careful of the potential compromises that choice may entail.

Thermal design is an important next step in the process. Designers should be sure they have the necessary space within the envelope to design a heat sink to effectively keep the LEDs in the system cool. For example, a 100W-equivalent A-19 replacement LED bulb does not exist — yet. Designing a system without adequate thermal management will also cause the LEDs to potentially underperform customer expectations.

Optical design is an important consideration as well. Directing the light effectively onto the required target will minimize the number of LEDs and power required to drive the system. This could, in fact, lower the overall cost of the system.

Designers also need to consider electrical design. LEDs are current-driven devices. There are several ways to design a constant current driver. Drivers that are simpler and more cost effective tend to be less efficient as well. Depending on the application, it is important to select the appropriate driver to meet the desired results.

Solid-state lighting solutions are only as strong as their weakest component.

Depending on the application, designers should be aware of the allowable compromises they can make in order for LEDs to become the leading technology light source.
