4 Summary

The MCU provides flexibility in SBS and allows the user to make the SBS as complex or simple as needed. The MCU allows for flexibility of part selections that others are incompatible together due to differing communication protocols. This application note illustrates the setup of SBS where the MCU polls charging current and charging voltage from the gauge and transmits to the charger, but more alerts and functionality can be added based on user needs. Rather than polling, interrupts must be implemented for efficiency and settings need to be chosen carefully so that the parts work in unison.
