The DS2762 is a high-precision Li+ battery monitor tailored for cost-sensitive battery pack applications. It integrates precise temperature, voltage, and current measurement, nonvolatile (NV) data storage, and Li+ protection into the small footprint of either a TSSOP package or flip-chip package.
The DS2762 is a high‑precision Li+ battery monitor that integrates temperature, voltage, and current measurement, non‑volatile data storage, and safety‑protection features in a compact TSSOP or flip‑chip package. It is intended for cost‑sensitive battery‑pack applications such as PDAs, cell phones, and digital cameras.
The document provides absolute maximum ratings, recommended operating conditions, detailed electrical characteristics, pin descriptions, and a selector guide for the various package and sense‑resistor options. It also includes a block diagram, application example, and ordering information.
