SLUSDQ4 April 2019 BQ79606A-Q1
The BQ79606A-Q1 integrates 8, high accuracy Delta-Sigma ADCs for measuring the cell and other voltages in the system. The cell voltages are monitored using 6 independent ADCs to enable simultaneous measurements. An additional ADC is integrated to measure external NTCs or voltages as well as other internal rails. The DIE temperature is monitored using a dedicated ADC. Each sense input, VC0 to VC6, is intended to connect to the single cell of a battery stack or the module connector of a sub-stack in the system. Each block contains a Delta-Sigma analog to digital converter (ADC) that samples and converters the voltage present between the pins VCn and VCn-1 during a sample.
