Description for the BQ27320

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.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
