Visão Geral

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

BQ2000TPWR is an older TI single‑cell Li‑ion protection/gauge IC; there isn’t a direct drop‑in cross. Depending on your needs:
- Protection only: BQ29700/BQ29x0 family
- Coulomb-counting gauge: BQ27441 (and newer BQ27426/27450)
- Integrated protection+gauge: BQ40Z60 family
Use TI’s cross-reference tool to confirm exact equivalents and package options.

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.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: American multinational corporation that designs and manufactures semiconductors and integrated circuits, specializing in analog and power-management products and embedded processing.

Application

BQ2000TPWR is a standalone battery fuel gauge IC. It’s used to monitor rechargeable packs and provide state-of-charge (SOC) and battery health data. Typical applications:
- Portable electronics and battery packs (Li-ion/Li-polymer; NiMH where supported)
- Cordless tools and other battery-powered equipment
- Portable medical devices and handheld instrumentation
- Uninterruptible power supplies (UPS) and telecom backup batteries
- RC toys and hobbyist devices
- Small energy-storage applications
Key functions include coulomb counting, temperature sensing, and SOC estimation to optimize runtime and protection.

Package

BQ2000TPWR uses TI’s PowerPAD package (PWR suffix) — a thermally enhanced PowerPAD style package.
