This product is a high-precision lithium-ion battery monitor with overvoltage protection, overcurrent/short-circuit protection, undervoltage protection, and zero-volt battery recovery charging.
The DS2761 is a high‑precision Li+ battery monitor that integrates temperature, voltage, and current measurement with safety‑protection functions. It is designed for cost‑sensitive battery‑pack applications and communicates via a Dallas 1‑Wire interface.
Key features include internal or external sense‑resistor options, 12‑bit bidirectional current measurement, 4.88 mV voltage resolution, 0.125 °C temperature resolution, lockable EEPROM, and programmable I/O for external control.
