Voltage and current monitor

9 June 2010 Power Electronics / Power Management

New from austriamicrosystems is the AS8002, an integrated solution for voltage and current monitoring in power inverters, especially targeted for grid connected systems such as solar photovoltaic inverters. 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 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 IC is available in a 4 x 4 mm QFN-16 package, operates from 3,0 V to 3,6 V and is specified for an operating temperature range of -40°C to +125°C.
