More Information

The BQ7965x-Q1 family of devices provides high-accuracy cell voltage measurements for a minimum of 6S to a maximum of 12S (BQ79652-Q1), 14S (BQ79654-Q1), or 16S (BQ79656-Q1) battery modules in less than 200 µs while these devices also support shunt-resistor current sense measurement. The integrated front-end filters enable the system to implement with simple, low voltage raring, differential RC filters on the cell input channels. The integrated, post-ADC, low-pass filters enable filtered, DC-like, voltage measurements. This family of devices also supports integrated current sensing capabilities with option to synchronize with cell voltage measurements for better state of charge (SOC) calculation. The device supports autonomous internal cell balancing with temperature monitoring to auto-pause and resume balancing to avoid an overtemperature condition.
