Description

BQ27520YZFT-G4 is a Texas Instruments single‑cell Li‑ion fuel gauge IC. It uses Coulomb counting plus TI’s Impedance Track algorithm to accurately estimate state of charge (SOC) and monitor battery health aging. Key outputs include SOC, remaining capacity (RM), full charge capacity (FCC), design capacity, voltage, current, temperature, and status flags. It communicates with a host MCU over I2C/SMBus, supports automatic learning/calibration, and stores battery parameters in its registers. The -G4 suffix denotes a specific production/package variant (RoHS-compliant). Typical applications are smartphones, tablets, ultrabooks, and other portable devices or smart battery packs that require accurate, real-time fuel gauging.

Features

Here are the main features of the BQ27520YZFT-G4 (TI single‑cell gas gauge with Impedance Track):
- TI Impedance Track technology for accurate state-of-charge (SOC), remaining capacity (RemCap), and full-charge capacity (FCC).
- Model-based coulomb counting with automatic capacity learning and aging compensation.
- Estimates SOC, SOH, RemCap, FCC; supports runtime forecasting.
- On‑chip sensing: voltage, current, temperature, and impedance measurements for robust gauging.
- End-of-discharge/charge monitoring with programmable voltage thresholds.
- I2C/SMBus digital interface with registers, alerts/interrupts, and programmable parameters.
- Programmable design parameters (design capacity, empty/full thresholds) and nonvolatile data flash for calibration data.
- Low-power operation with wake/sleep capability suitable for portable devices.
- Small RoHS-compliant package (G4 variant), typically 8-pin.
- Self-contained gauge requiring no external MCU for gauging logic.

Package

It uses a 20-pin VQFN package (4x4 mm).

Pinout

- Pin count: 16 pins (VQFN-16 package, BQ27520YZFT-G4).
- Function: Battery fuel gauge (gas gauge) IC for Li‑ion cells; provides coulomb counting, voltage/temperature monitoring, and SoC/SoH estimation, with SMBus/I2C communication to the host.

Manufacturer

The BQ27520YZFT-G4 is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures a broad range of integrated circuits, specializing in analog, mixed-signal, and embedded processing solutions.

Application

Single-cell Li‑ion/Li‑polymer battery fuel gauge (SMBus/I2C). Applications: mobile/portable devices and battery packs—smartphones, tablets, wearables, cameras, handheld scanners, portable medical devices, and other consumer electronics requiring accurate state-of-charge, voltage, current, temperature, and health data.

Equivalent

Direct one-to-one equivalents don’t exist. BQ27520YZFT-G4 is TI’s Impedance-Track Li‑ion fuel gauge. Closest TI substitutes are other gauges in the BQ27x2x family with similar features and cell counts. For cross‑vendor options, consider Maxim MAX17043/MAX17044 or Renesas ISL94202 as alternatives.
