Extend battery life in portable devices with new ultra-low Iq LDO Microchip announces a linear Low Dropout (LDO) regulator that extends battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs. With an ultra-low Iq of 250 nanoamps (nA) versus the approximate 1 uA operation of traditional devices, the MCP1811 LDO reduces quiescent current to save battery life, enabling end-users to recharge or replace batteries less often. The minimised power consumption enables portable electronic devices to run for months or even years on a single battery. Ideal for IoT and battery-operated applications such as wearables, remotes and hearing aids, the 250 nA ultra- low Iq reduces power consumption in applications by minimising standby or shutdown current. Reducing standby power consumption is critical in remote, battery-powered sensor nodes, where battery replacement is difficult and operating life requirements are high. Available in package options as small as 1 x 1 millimeter (mm), the MCP1811 consumes minimal board space to meet the needs of today’s compact portable electronic designs. Depending on the application and number of LDOs, designers can take advantage of the extra board space with a larger battery to further increase battery life. An additional benefit offered by the MCP1811 is faster load line and transient response when compared to other ultra-low Iq LDOs. Faster response times can accelerate wake-up speed in devices such as monitors or sensors that require immediate attention. Faster transient response can help designers to avoid undervoltage and overvoltage lockout measures used in sensitive applications where transient spikes can result it catastrophic results. The MCP1811 is available today for sampling and in volume production in packages down to a 1 x 1 mm DFN. For more information, visit: MCP1811 LDO

Infineon to drive edge-computing based applications running on Amazon Web Services Semiconductors are key components for the Internet of Things (IoT). They connect the real with the digital world now evolving to cloud services and artificial intelligence (AI) functionality. Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) allows for easy and secured use of new generation sensors featuring new AI functionalities running on Amazon Web Services (AWS). “Infineon supports the development of secured cloud connection-enabled applications,” said Sandro Cerato, Chief Technology Officer of the Power Management & Multimarket Division at Infineon. “These can range from mere motion detection up to situational awareness, by leveraging AI and machine learning algorithms. We are combining leading-edge sensors, hardware-based security and Infineon microcontrollers, with the technology and services provided by AWS to support customers with the next level of smartness”. Infineon’s XMC4000™ family of 32-bit-microcontrollers now supports Amazon FreeRTOS, a microcontroller operating system that makes small, low-power edge devices easy to program, deploy, secure, connect, and manage. Key success factors for IoT comprise hardware-based security solutions and industry-leading sensor technology. With their smart interplay, multiple new options of edge- computing based applications for consumer and industrial markets are enabled. Securely connecting manufacturers’ devices both locally and to the cloud is paramount for customers to take up the connected service offering. People living in smart homes and working in smart buildings can benefit from the seamless interaction of the new generation XENSIV™ sensors. Radar, pressure sensors and MEMS microphones are accompanied by OPTIGA™hardware security solutions. Infineon-enabled solutions in energy, light management, health care and building operation running on AWS can improve the quality of life and deliver substantial cost savings. For example, Infineon’s XMC4800 family Connectivity kit WiFi runs on AWS. This development platform brings edge-computing services to the next level of interaction in customers’ applications, including WiFi connectivity and ETHERCAT. “Using the XMC4800 series, Infineon has the opportunity to be one of the first movers in the market offering AWS FreeRTOS combined with ETHERCAT functionality,” said Ralf Koedel, Director Product Marketing
