'Highest accuracy available' from battery management data acquisition front end IC
1 min read
austriamicrosystems has announced a high precision data acquisition front end ic for automotive battery current, voltage, temperature sense applications. According to the analogue ic manufacturer, the AS8510 features the 'highest accuracy available'. The device has also been designed for sensor interface applications where precise measurement of small signals close to ground is required.
According to austriamicrosystems, it is the first to feature a 16bit dual channel a/d converter plus programmable gain amp architecture with less than 1LSB of offset and noise. The AS8510, in combination with the company's 'System Basis Chip' and a mcu, is said to provide an entire battery sensor semiconductor solution for both high side or low side.
The IC incorporates two independent analogue input channels with 16bit a/d converters, each with individually programmable sampling rates. Each channel has a low drift programmable gain amplifier for handling ±160mV signals or 0 to 1V when by passing the PGA, thus battery currents from mA to kA can be measured.
Manfred Brandl, austriamicrosystems' product manager automotive sensor interface and SBC ASSPs, said: "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. With the AS8510, designers have the highest accuracy available and the flexibility required for a wide variety of applications. In addition, by adding an austriamicrosystems LIN companion IC and a low cost microcontroller, automotive applications can realise reduced time to market in an evolving field at competitive price and improved performance."
The AS8510 is available in a SSOP20 package, operates from 3.3V and has an ambient operating temperature range of -40 to 125°C.
