This document describes a high-precision Li-Ion battery monitor with features such as overvoltage protection, overcurrent/short circuit protection, and undervoltage protection. It is available in two configurations with different current measurement and accumulation ranges. The device also supports voltage measurement and temperature measurement using an integrated sensor. It has system power management and control feature support, low power consumption, and includes a Dallas 1-Wire interface. The document provides detailed pin assignment and description.
The DS2760 is a high‑precision Li‑Ion battery monitor that integrates temperature, voltage, and current measurement with safety protection and non‑volatile memory. It supports both internal (25 mΩ) and external user‑selectable sense resistors and communicates via a 1‑Wire interface with a unique 64‑bit address.
The document provides a complete pin description, ordering information, electrical characteristics, power‑mode behavior, and protection circuitry details, enabling designers to implement accurate battery monitoring, capacity estimation, and safety features in cost‑sensitive battery pack applications.
