Description for the BQ75614-Q1

The BQ75614-Q1 device provides high-accuracy cell voltage measurements up to 16S 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 rated, differential RC filters on the cell input channels. The integrated, post-ADC, low-pass filters enable filtered, DC-like, voltage measurements. This device 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.

This device also includes eight GPIOs or auxiliary inputs that can be used for external thermistor measurements.

Host communication to the can be connected via the device's dedicated UART interface.
