BQ2060A-E619DBQR

The bq2060A-E619DBQR is a Texas Instruments battery fuel gauge IC for single‑cell Li‑ion/Li‑polymer packs. It uses coulomb counting to track remaining capacity and provides state-of-charge (SOC), voltage, current, and temperature monitoring with a two‑wire interface (I2C-like) to a host microcontroller. Key features typically include programmable full‑scale capacity, non‑volatile calibration data storage, status/alert outputs, and low quiescent current in sleep. The E619DBQR suffix denotes the specific package/revision (date code/lot) of this device.
Typical applications include battery packs for handheld devices, wireless peripherals, portable instruments, and other consumer/industrial electronics.
Implementation note: it requires an external sense resistor; refer to TI reference designs for proper connection to the pack, sense resistor, and host interface.

Key features of bq2060A-E619DBQR (standalone Li‑ion/Li‑polymer gas gauge):
