ADS131B24-Q1 High-Voltage Battery Pack Monitor Texas Instruments ADS131B24-Q1 High-Voltage Battery Pack Monitor is a fully integrated monitor for automotive electrical vehicle (EV) battery management systems (BMS). The ADS131B24-Q1 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.
