May 17, 2010 – austriamicrosystems announced the AS8002 integrated solution for voltage and current monitoring in power inverters. This single-chip design offers improved performance and reduced system cost of power inverters while allowing simplified design with a reduced number of components. The AS8002 is especially targeted for grid connected systems such as solar photovoltaic inverters. The chip offers advantages over alternative approaches for monitoring electrical power injected into the grid. austriamicrosystems’ AS8002 allows the use of low-cost resistors for current and voltage sensing. The sensed voltage and current are directly available in high-resolution digital format. The chip’s flexible front-end provides adjustable gain to accommodate various resistor values, and on-chip calibration allows compensation for external component inaccuracies as well as variations over temperature. Added features like fast over-current detection provide additional safety. These features make the AS8002 also attractive for other power monitoring applications, such as wind turbines and uninterruptible power supplies. The AS8002 is available in a 4x4 mm QFN-16 package, operates from 3.0 V to 3.6V and is specified for an operating temperature range of -40 to +125°C.Price & AvailabilityThe AS8002 integrated measurement IC is available now at a 1k price of $5.31. Technical SupportAn application board is available.
