Austriamicrosystems, a global designer and manufacturer of analog ICs, has introduced its new integrated voltage and current measurement IC, AS8002 for power inverters.

According to Austriamicrosystems, the single chip design offers reduced system cost of power inverters while allowing simplified design with a reduced number of components.

The company claims that the AS8002 is especially targeted for grid connected systems such as solar photovoltaic inverters and offers advantages over alternative approaches in terms of monitoring the signals injected into the grid.

the IC 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 front-end provides adjustable gain to accommodate various resistor values and on-chip calibration allows compensation for external component inaccuracies and variations over temperature.

In addition, features like fast over-current detection provide additional safety. These features make the AS8002 suitable for other power monitoring applications, such as wind turbines and uninterrupted power supplies.

The AS8002 is available in a 4×4 mm QFN-16 package, operates from 3.0V to 3.6V and is specified for an operating temperature range of -40 to +125 degree centigrade.

Michael Leitner, director of marketing business unit industry and medical at Austriamicrosystems, said: ”For economic, safety and regulatory reasons, electrical energy injected to a power grid must be accurately monitored.

”As the need for grid monitoring continues to grow, the AS8002 will replace a number of solutions that suffer from higher cost, lower accuracy or poorer performance.”
