The Texas Instruments bq27530-G1 system-side Li-Ion Battery Management Unit is a microcontroller peripheral that provides Impedance Track? fuel gauging and charging control for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development. Together with bq2416x Single-Cell Switchmode Charger, the bq27530-G1 manages an embedded battery (non-removable) or a removable battery pack.
The bq27530-G1 uses the patented Impedance Track? algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (min), battery voltage (mV), temperature (°C), and state-of-health (%).
