GLF Integrated Power offers two versions of AEC-Q100 grade load switch ICs

Fri, Oct 07, 2022

Two versions of the IQSmart IC load switches are offered by GLF Integrated Power. The AEC-Q100 qualified ICs have a wide temperature range, with one version featuring true reverse current blocking.

The GLF1111Q and GLF1200Q low power load switches are rated for a wide temperature range (-40 to +125 degrees C). The GLF1111Q provides industry-leading, battery-saving leakage current of 2nA, typical, said GLF. 

The GLF1200Q features a true reverse-current blocking, which prevents a backup power source from being discharged when an input node is shorted. The GLF1200Q, therefore, works all of the time regardless of on or off state.

Applications for the GLF1111Q and GLF1200Q include infotainment and cluster display systems, diagnostic systems, passive entry / start systems, customer premise equipment (CPE), face recognition systems and intelligent cockpit and autonomous driving applications. 

Both the GLF1111Q and GLF1200Q IQSmart devices are packaged in a SOT-23-5L and offer easy visual inspection of solder joints. Both ICs also feature integrated slew rate control that limits inrush upon turn on, therefore minimising the effects of voltage droop. 

Each load switch IC supports a wide input voltage range of 1.5 to 5.5V. A single device can therefore be used in a variety of voltage rail applications, helping to simplify inventory management, said GLF. Both ICs are also offered with an optional output discharge switch.

“The GLF1111Q and GLF1200Q address the ever-expanding, evolving range of automotive electronic systems that require a high-performance load switch with a wide-ambient operating temperature range to assure reliable, long-term operations,” explained Eileen Sun, president and CEO at GLF Integrated Power.

GLF integrated Power is a fabless semiconductor company based in Santa Clara, California, USA. It was founded in 2013 in response to the IoT, portable and wearable ‘revolution’. The company supplies efficient, small, silicon power control and protection ICs and has developed IP that enables cost-effective, efficient and differentiated power management solutions.

Digital pixel readout IC works with existing technology

Fri, Oct 07, 2022

Able to work with existing detector and optics technology, the Calcium high dynamic range digital pixel readout IC is available from Senseeker Engineering in an industry standard format and available for commercial use.

The 20 micron, 640 x 512mm Calcium RP0033 DPROIC (digital pixel readout IC) has a dynamic range above 120dB and a frame rate of up to 700 frames per second. 

It can be used with existing detector and optics technology, said Senseeker. Customers can accelerate development of high dynamic range, infrared focal plane arrays (FPAs) by hybridising available off-the-shelf detectors with this advanced commercial readout, explained the company.

The Calcium RP0033 has dual gain modes and programmable well capacities of over 40 Me- and 400 Me-, each with low read noise of 50 and 330 electrons at 80K, respectively. The chip is controlled through Senseeker’s SenSPI serial peripheral interface to facilitate communications. It can operate in both integrate-then-read and integrate-while-read modes and has programmable windows to observe and track targets at thousands of frames per second. 

“This chip is designed to make extremely advanced digital pixel technology accessible to everyone,” said Senseeker’s president, Kenton Veeder. Developers can attach a detector and drop the IC behind existing optics or in a Senseeker sensor test unit to begin imaging with single-digit mK NETD.

Senseeker’s Calcium architecture is stitchable up to a 4k x 4k array size. This allows the proven base design to be electronically stitched together in blocks of 512 x 512 rows and columns to grow a family of DPROICs from small to very large formats.  Larger format Calcium DPROICs are already in development, with a 2k x 1k unit coming soon.

The Calcium RP0033 is in production now and is supported by an electronics evaluation kit also available from Senseeker. 

The Calcium DPROIC is already being used by QmagiQ to develop SLS FPAs for the next generation of infrared imaging, revealed Mani Sundaram, president and CEO at QmagiQ.

Six external magnetic mount antennas serve 5G, ISM and LPWA applications

Thu, Oct 06, 2022

Linx Technologies has introduced six external magnetic-mount antennas serving 5G cellular, ISM (industrial, scientific and medical) and low power wide area (LPWA) applications.

Two models, the ANT-2.4-MMG1-SMA and ANT-2.4-MMG2-SMA are designed for Wi-Fi / WLAN and 2.4 GHz ISM band applications such as Bluetooth and Zigbee. 

Two others, the ANT-5GW-MMG1-SMA and ANT-5GW-MMG2-SMA antennas are designed for 5G New Radio, LTE and cellular IoT (LTE-M, NB-IoT) applications. 

The final pair, the ANT-8/9-MMG1-SMA and ANT-8/9-MMG2-SMA antennas are designed for use in 868 and 915MHz bands for low power wide area (LPWA) applications such as LoRaWAN and Wi-Fi HaLow, as well as ISM and remote control applications.

All six antennas provide ground plane independent dipole antenna options which mount to ferrous metallic surfaces via an integrated magnetic base. The antennas terminate in an SMA plug (male pin) connector on a one, two or three metre length of RG-174/U coaxial cable.

The magnetic mount antennas enable users to expand the reach of their systems by mounting the antenna away from the radio, commented Rick Stuby, Linx Technologies’ vice president of product management. The small size makes them inconspicuous and easy to manage, he added.

The magnetic mount antennas are available now via Linx Technologies’ distributor and manufacturer representative networks.

Linx Technologies strives to minimise the risk, delays, and technical challenges for design engineers to make products wireless and connect them to the IoT. 

Linx manufactures wireless components including antennas, RF connectors and cables, RF modules and remote controls. The company is part of TE Connectivity, a sensor and connectivity provider whose products are proven in the harshest environments, enable advancements in transportation, industrial applications, medical technology, energy, data communications and the home, said the company.

5Mpixel image sensor is sensitive for professional security cameras

Thu, Oct 06, 2022

The OS05B is a 5Mpixel CMOS image sensor has a 2.0 micron pixel in a 1/2.78 inch optical format that has high sensitivity and dynamic range for professional and high end security cameras, said Omnivision.

The OS05B CMOS image sensor can also be used in industrial and factory surveillance systems, webcams and high-end baby monitors. It is based on the PureCel Plus technology and features Omnivision’s Nyxel near-infrared (NIR) technology for crisp, clear images in low light conditions.

According to Cheney Zhang, senior marketing manager at Omnvision, the OS05B, is available as an upgrade to the OS05A image sensor, introduced five years ago. It is claimed to have the best NIR QE and low-light performance in a 5Mpixel, small package size. “The OS05B is ideal for professional security cameras, for example in industrial and factory applications, where it is important to capture clear video at night while also maintaining low power,” he added.

Signal to noise ratio has been improved by 32 per cent, compared with the OS05A, and NIR QE at 940nm is improved by 24 per cent. The OS05B also has selective conversion gain which increases sensitivity and reduces the readout noise level for optimum SNR under low-light conditions. Low conversion gain also achieves a higher full well capacity in bright conditions. It captures high resolution video at 60 frames per second with two-exposure staggered HDR. The OS05B supports MIPI and LVDS interfaces. 

Samples of the OS05B are available in Q4 2022, and it will be in mass production in Q1 2023. 

Omnivision is a global fabless semiconductor organisation that develops advanced digital imaging, analogue and touch and display solutions for multiple applications and industries, including mobile phones, security and surveillance, automotive, computing, medical and emerging applications.
