The BQ27210DRKR is a battery monitor from TI's bqJUNIOR™ series designed for single-cell Lithium Ion or Lithium Polymer packs. It reports remaining capacity, voltage, and current to a host microcontroller over an I²C interface — the standard data bus for portable electronics.
It is a battery monitor IC for single-cell Lithium Ion/Polymer packs, reporting capacity, voltage, and current to a host over an I²C bus.
Yes, the I²C interface is the only communication bus on this monitor — the host reads fuel-gauge data over it.
