Description for the BQ27620-G1

The Texas Instruments bq27620-G1 system-side is an easy configure microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires minimal user configuration and system microcontroller firmware development.

The bq27620-G1 uses the patented Impedance Track™ algorithm with Dynamic Voltage Correlation for fuel gauging. This patented process eliminates the need for a when calculating remaining battery capacity (mAh), state-of-charge (%), run-time to empty (min), battery voltage (mV), temperature (°C) and state of health (%).

Battery fuel gauging with the bq27620-G1 requires connections only to PACK+ (P+), PACK- (P-), and Thermistor (T) connections to a removable battery pack or embedded battery circuit. The CSP option is a 15-ball package in the nominal dimensions of 2610 × 1956 µm with 0,5 mm lead pitch. It is ideal for space constrained applications.
