A45E_EETimes_2-375x10_87_A45.qxd 2/1/13 11:19 ZigBee transceivers offer Deep Packet Inspection GreenPeak Technologies has introduced a new generation of ZigBee transceivers which contains a coexistence scheme that allows Wi-Fi, Bluetooth and ZigBee chips to work side by side in the same device. The GP501 also contains Deep Packet Inspection allowing deep sleep modes of set-top boxes and other host 100 to 10,000 devices by means of Wake-on-LAN messages. ZigBee shares the 2.4 GHz VDC Outputs DC-DC CONVERTERS frequency band with other Wi-Fi equip‑ment. 4 Watt to 10 Watt Series Surface Mount & Plug In Over 250 Standard Models! Isolated Outputs/ Proportional V in and V out Miniature fully encpsulated modules for operation in rugged environment Military options available Expanded operating temperature -55º to +85º C Ambient • Military Standard 883 Selected testing available Will review all Customer Specifications for custom design specifications Over 2,500 standard high and low voltage DC-DC converters and AC-DC power supplies Industrial/Cots/Military Isolated/Regulated/Proportional/ Programmable Also Thousands of Hi reliability, Ultra Miniature Transformers and Inductors US Manufactured since 1969 See PICO’s full line catalog at www.picoelectronics.com PICO ELECTRONICS, Inc.

E-mail: rbennett@ginsbury.co.uk Phone: 0044 1634 298900 Fax: 0044 1634 290904 The GP501 has a coexistence interface to allow optimized and colocated ZigBee/Wi-Fi radios to work in the same device, successfully avoiding RF interference when operating simul‑taneously. The coexistence interface enables arbitration over the shared radio frequency medium to prevent conten‑tion, signal degradation and data loss. Another advantage of the GP501 is its small size: the device’s 32-pin 5x5 mm2 footprint allows integration into even the smallest product form-factors. GreenPeak Technologies www.greenpeak.com Single-cell battery charger ICs with I2C and USB OTG TI’s bq2419x family of 4.5-A out‑put, 20-V input-rated switch-mode chargers with I2C interface and USB On-the-Go (OTG) sup‑port delivers faster and cooler charging to a wide array of applica‑tions ranging from power banks and packs to 4G LTE routers, Wi-Fi speak‑ers, portable medical and industrial designs. The switch-mode charger achieves 92-percent efficiency at 2A and up to 90-percent efficiency at 4A of output current. The device also meets Energy Star and Euro‑pean Union charging specifications. Programmable thermal regulation temperature improves system-level design. An integrated battery dis‑charge MOSFET provides the indus‑try’s lowest on-resistance of 12 mΩ. Texas Instruments www.ti.com Waterproof remote control system for home automation RF Solutions’ Elite remote control sys‑tems are delivered ready-to-use includ‑ing the sleek handheld and fully water‑proof receiver containing four relays suitable for loads up to 230V/1kW, enabling users to control garden lights, water features or other outdoor electrics such as pow‑ered gates. Operating in the license-free 868MHz band, the receiver is housed in a rugged IP68 enclosure designed to be installed permanently outdoors. The unit is wall mountable and provides a choice of 10 cable entry points for ease of installation. Each of the four outputs can be set to operate in timed, momentary or latching mode. The transmitter buttons can be configured to control any relay in the receiver using RF Solutions “Easy Learn” process. The receiver provides an easy to use sync/pair button allowing one-press auto pairing, and also has an in-built signal test mode, timer set and erase buttons. RF Solutions www.rfsolutions.co.uk Power supplies with built-in waveform generation The TDK-Lambda Z+ Series of highdensity, 2U format benchtop and rack mounted 200W and 400W power supplies have the ability to create and store up to four application-specific test waveforms, removing the need for an external controller in basic simulation tasks. Up to 12 values can be programmed using the waveform creator software provided and four waveforms can be stored in the Z+ unit’s memory. More complex wave‑forms can be created using LabView. These waveforms can be either repetitive or single-shot and injected into the system under test and the re‑sults analysed confirming the proper operation of the powered system or pinpointing a fault. Once stored the programme can be run remotely or recalled and run directly using the Z+ front panel controls obviating the need for a computer connection if preferred.
