 Vishay introduced a AEC-Q101-qualified, 40V n-channel TrenchFET power MOSFET. Specifically for heavy duty automotive applications, the SQM200N04-1m1L is Vishay's first power MOSFET to take advantage of the low resistance contribution and very high current rating of the 7-pin D²PAK package. When combined with Vishay's high-density n-channel TrenchFET technology, the result is an on-resistance of 1.1mΩ max at 10V and 1.3mΩ max at 4.5V.

 

In addition, a continuous drain current of 200A can be sustained, allowing engineers to create robust designs with an additional margin for safety-critical applications. The SQM200N04-1m1L is optimized for high-power automotive motor drive applications, including electric power steering.

 

The device is designed and 100 % tested in production to withstand single pulse avalanche events of 100A and 500mJ. It features thermal resistance of 0.4°C/W (junction to case), and an operating temperature range of - 55°C to + 175°C. The SQM200N04-1m1L is RoHS-compliant, halogen-free, and 100% Rg and UIS tested.

 Energy Micro announces a partnership with Lamprey Networks to provide energy friendly, secure and certified remote monitoring medical electronic systems. Using a standard EFM32 starter-kit and HealthLink PC tools, the design includes a USB driver and communications protocol stack certified by Continua Health Alliance. Continua is the international industry organization dedicated to advancing personal connected health by promoting end-to-end, plug-and-play connectivity of personal health devices and establishing industry standards for interoperability.

 

The demo platform is based on the USB versions of Energy Micro’s EFM32 Leopard and Giant Gecko ranges of Cortex-M3 based microcontrollers. It will also be applicable to the forthcoming Cortex-M4 floating-point Wonder Gecko. The energy efficient 32-bit design facilitates development of patient monitoring systems, including blood glucose monitors and a fast-growing number of mobile healthcare devices, many of which require high performance processing matched to the lowest possible energy consumption in order to maximize battery life.

 

In addition to USB stacks, LNI provides implementations of their HealthLink interface and protocols that operate on common platforms such as Android, Windows, Linux and iOS. This enables users to transfer health and fitness data via multiple transports such as Bluetooth, Bluetooth LE and Zigbee directly to Continua receivers. Individuals and healthcare professionals can then store and maintain this information on the Microsoft HealthVault internet platform. Devices can also be configured to communicate over a cloud network using LNI’s HealthLink Cloud, a software development kit for back end servers that sends and receives WAN measurement data and enables this to be shared across the health ecosystem.

 

The Energy Micro/LNI demonstration is available free for EFM32 Giant Gecko STK users. A software example is freely available in Simplicity Studio suite from Energy Micro, and the HealthLink PC software from Lamprey can be found at the KNI website.
