AS8510

Data Acquisition Device for Battery Sensors

ꢀ

Option for multiplexing either one differential

input, or two single ended inputs or the internal temperature

sensor on one channel

1 General Description

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.

ꢀ

Programmable current source for external temperature sensor

connectable to any of the inputs

ꢀ

High precision and high stability 1.2V reference voltage source

Digital signal processing with filter options for both channels

Four operating modes providing

- Continuous data acquisition (or)

- Periodic single-shot acquisition, (or)

- Continuous acquisition on threshold crossing of programmed

current levels (or)

After analog to digital conversion and digital filtering, the resulting

16-bit digital words are accessible through 4-wire standard serial

interface.The device includes a number of additional features

explained in the next section.

- A combination of the above

ꢀ

On chip high-precision 4MHz RC oscillator or option for external

clock

ꢀ

-40ºC to +125ºC ambient operation

AEC - Q100 automotive qualified

Internal chip ID for full traceability

SSOP-20 pin package

2 Key Features

ꢀ

3.3V supply voltage

Two High resolution 16 bit Σ−Δ A/D converters

Programmable sampling to enable data throughputs from less

than 1Hz to 8kHz

3 Applications

The AS8510 is ideal for shunt based batteries sensor. For high-side

current sensing, the input signal may be conditioned using

ꢀ

Zero Offset for both channels

Independent control of data rate on both channels

Precision, low noise, programmable gain amplifiers for both

channels with gains 5, 25, 40, 100 to support wide dynamic

ranges.
