3 Description
The ADS131B26-Q1 is a complete analog front-end
(AFE) for automotive electrical vehicle (EV) battery
management systems (BMS) that 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 overcurrent detection comparators work in
parallel to the two ADCs for fast overcurrent detection.
Another set of two simultaneous-sampling, 24-bit
ADCs (ADC3A, ADC3B) is integrated to measure
battery pack voltage using external high-voltage
resistor dividers synchronously to the battery current
for accurate state-of-charge and state-of-health
battery calculations.
Additional two, multiplexed, 16-bit ADC channels
(ADC2A, ADC2B) are available to measure shunt
temperature using external temperature sensors, such
as thermistors or analog output temperature sensors,
as well as other voltages in the system.
A multitude of monitoring and diagnostic features are
integrated in the device to mitigate and detect random
hardware faults to aid in the development of functional
safe BMS.
The ADS131B26-Q1 is offered in a 48-pin HTQFP
package and is specified over the automotive
temperature range of –40°C to +105°C.
