Description

General part information

ADS131B23 Series

The ADS131B23 is a fully integrated, high-voltage, battery-pack monitor for industrial battery management systems (BMS).

The ADS131B23 integrates two simultaneous-sampling, high-precision, 24-bit ADC channels (ADC1A, ADC1B) to redundantly measure battery current with high resolution and accuracy using an external shunt resistor. Two independent digital comparators enable fast overcurrent detection in parallel with the two ADCs.

An additional multiplexed, 16-bit ADC (ADC2A) is available to measure shunt temperature and other voltages in the system, such as battery-pack voltage, using external high-voltage resistor dividers. Shunt temperature is measured using an external temperature sensor, such as a thermistor or an analog output temperature sensor. ADC2A is equipped with a channel sequencer that automatically steps through the configured multiplexer inputs to reduce communication on the SPI.
