Description

AD7280AWBSTZ is an Analog Devices battery‑gauge IC (AD7280A family) used for monitoring Li‑ion/Li‑poly packs. It provides multi‑cell coulomb counting, state‑of‑charge (SOC) estimation, and sensing of cell voltages, pack current (via a sense resistor), and temperature. It includes a built‑in control/ADC engine and communicates with a host MCU through a serial interface (SPI‑/UART‑style as supported by the device). It supports configuration, calibration, and programmable thresholds for alerts. Typical applications include battery packs for tools, medical devices, and portable electronics where accurate SOC and health information is required. The WBSTZ suffix selects a specific package/temperature range; consult the datasheet for exact pinout, package type, RoHS status, and ordering details.

Features

AD7280AWBSTZ features (concise):
- Standalone Li-ion/Li-polymer gas gauge for 2–4 cell packs.
- Coulomb counting with SOC estimation; programmable design capacity and learned capacity.
- Voltage, current (via external sense resistor), and temperature monitoring with integrated ADC.
- I2C-compatible digital interface with register map; interrupts/alerts output.
- Programmable alarm thresholds and flags for fault conditions.
- Low quiescent current with fast wake/sleep modes.
- Safety protection: overvoltage, undervoltage, overcurrent, and overtemperature reporting.
- Non-volatile calibration/compensation data storage for long-term accuracy.
- Suitable for compact packages (WBSTZ) with standard industrial temperature range.

Package

AD7280AWBSTZ comes in a 28‑lead TSSOP package (28‑pin, wide‑body SOP), RoHS compliant.

Pinout

- Pin count: 28 pins
- Function: A multi-cell Li-ion battery monitor/gauge IC. It measures multiple cell voltages (up to 8 cells), includes coulomb counting and temperature sensing, and communicates with a host microcontroller via a serial interface (SPI).

Manufacturer

- Manufacturer: Analog Devices, Inc. (Analog Devices)
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits and related products for industrial, automotive, consumer, and communications markets.

Application

AD7280AWBSTZ is a multi-cell Li‑ion/Li‑polymer battery monitor and gas gauge for 3–4 cell packs. Applications: battery management systems in notebooks/tablets/mobile devices; portable electronics; cordless tools; medical devices; energy storage systems; UPS/backup power; e‑bikes/scooters; smart battery packs needing coulomb counting, SOC estimation, voltage/temperature monitoring, and Delta‑V end‑of‑charge detection.
