Description
BQ2000TPWR is TI’s stand‑alone gas gauge (battery fuel gauge) from the BQ2000 family. It monitors a rechargeable pack’s health and charge status by coulomb counting, and also measures pack voltage and temperature to improve SOC accuracy. It can generate protective/status signals (e.g., low battery or fault) and maintains capacity data for the pack. The “TPWR” suffix marks a specific power/package variant of the device. This is an older, legacy gauge, often found in older NiMH/Li-ion pack designs, and features can vary by package and configuration. For exact specifications (supported cell count, interface, programming, timing, and electrical details), consult the BQ2000TPWR datasheet and TI application notes.
Equivalent

Pinout
Pin count: 28 pins.
Function: TI bq2000TPWR is a Li‑ion battery gauge/protection IC. It monitors cell voltage, current, and temperature, performs coulomb counting, and provides state-of-charge (SOC) information plus protection signals (over/under voltage, overcurrent) to the system; it communicates with the host via an I2C/SMBus‑style interface.
