AS8510 Analog Front-End
Battery management system
The AS8510 is a virtually offset free, low noise, two channel measurement device. It is tailored to accurately measure battery current from mA range up to kA range in conjunction with a 100 µΩ shunt resistor in series with the battery rail. Through the second measurement channel it enables capture of, either battery voltage synchronous with the current measurement, or, measure the analog output of an internal or external temperature sensor. Both channels are matched and can either measure small signals up to ±160 mV versus ground, through programmable gain amplifier or larger signals in the 0 to 1V range without the amplifier.
