    Pitch NanoFree™ (DSBGA) Package

The Texas Instruments single-cell bq27320 battery fuel gauge requires very minimal configuration and system microcontroller firmware development, leading to quick system bring-up. The bq27320 uses the Compensated End-of-Discharge Voltage (CEDV) gas gauging 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 (%).

TI customers can tune chemistry parameters using TI’s web-based tool, GAUGEPARCAL.

Configurable interrupts help save system power and free up the host from continuous polling. Accurate temperature sensing is supported via an external thermistor.

Battery fuel gauging with the bq27320 requires only PACK+ (P+), PACK– (P–), and optional thermistor (T) connections to a removable battery pack or embedded battery circuit. The device uses a 15-ball NanoFree™ (DSBGA) package. It is ideal for space-constrained applications.
