austriamicrosystems’ new battery management data acquisition front-end
2010-03-29
The highly flexible multi-channel AS8510 features unique zero offset for simultaneous voltage, current and temperature measurement in conventional, hybrid or electric vehicles.
austriamicrosystems, a designer and
manufacturer of high-performance analog ICs, today announced the AS8510, a high precision data acquisition front-end IC for automotive battery current, voltage, temperature sense applications and in general for sensor interface applications where precise measurement of small signals close to ground is required.
The new flexible sensor interface IC offers advantages over alternative solutions, including being the first to feature a 16-bit dual-channel ADC + PGA architecture with less than one LSB of offset and noise. Highly configurable, the AS8510 allows systems tailored to individual needs making it well suited for a wide range of present and future battery management applications. The AS8510 in combination with austriamicrosystems “System Basis Chip” and a micro controller provides an entire battery sensor semiconductor solution for both High-Side or Low-Side at a price below 2,8$ in volume.
The AS8510 data acquisition front-end IC features two independent analog input channels with 16-bit ADCs, each with individually programmable sampling rates. Each channel has a low-drift programmable gain amplifier for handling +/- 160 mV signals or 0V to 1 V when by-passing PGA, thus battery currents from the mA range to the kA range can be measured from 100 µ? shunt. A highly linear sigma delta architecture and wide range of sampling rates allows the AS8510 to provide flexible support of EV (electric vehicle) applications. The offset auto-zero feature (both channels) allows high accuracy measurements with low value shunt resistance (to 100 µ?) with negligible insertion loss. Also, various operating modes include low power standby with current monitoring for active wake-up.
“The need for increasingly more accurate and efficient power management is being driven by the exploding market for battery powered devices and, increasingly, electric vehicles,” stated Manfred Brandl, Product Manager Automotive Sensor Interface and SBC ASSPs at austriamicrosystems. He continued, “With
