Description

The AS8512 IVT-sensor is a data acquisition front-end IC empowering virtually offset free, low noise, 2-channel measurement of current and voltage in battery management systems. It is tailored to accurately measure wide range of current (from mA up to kA) in combination with a 100 µOhm shunt resistor connected in series with the battery rail. Through the second measurement channel it enables capture of either battery voltage synchronous with the current or to measure the analog output of an internal or external temperature sensor. It provides measurement outputs via a 4-wire SPI serial interface. With its accurate data acquisition and cost optimized capabilities the sensor is ideal for battery management systems for energy storage system (ESS).
