The BQ79616 device provides high-accuracy cell voltage measurements in less than 200 µs for 16-series battery modules in high-voltage battery management systems in HEV/EV. The monitor offers different channel options in the same package type, providing pin-to-pin compatibility and supporting high reuse of the established software and hardware across any platform. The integrated front-end filters enable the system to implement with simple, low voltage rating, differential RC filters on the cell input channels. The integrated, post-ADC, low-pass filters enable filtered, DC-like, voltage measurements for better state of charge (SOC) calculation. This device supports autonomous internal cell balancing with temperature monitoring to auto-pause and resume balancing to avoid an overtemperature condition.

The inclusion of the isolated, bidirectional, daisy chain ports supports both capacitor- and transformer-based isolation, allowing the use of the most effective components for centralized or distribution architectures commonly found in the Energy Storage System (ESS). This device also includes eight GPIOs or auxiliary inputs that can be used for external thermistor measurements.

Host communication to the BQ79616 device can be connected via the device’s dedicated UART interface or through a communication bridge device, BQ79600. Additionally, an isolated, differential daisy-chain communication interface allows the host to communicate with the entire battery stack over a single interface. in the event of a communication line break, the daisy-chain communication interface is configurable to a ring architecture that allows the host to talk to devices at either end of the stack.
