The BQ75614-Q1 device provides high-accuracy cell voltage measurements up to 16S battery modules in less than 200 µs. 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. Integrated current measurement 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. The device includes option to support fuse and relay open/close diagnostics. The device also includes eight GPIOs/auxiliary inputs that can be used for external thermistor measurements.
