Product details

Single-Cell Li-Ion Monitor with 1-Wire Interface

The DS2780G+ is a battery monitor from Analog Devices designed for single-cell Lithium Ion/Polymer packs. It communicates over a 1-Wire interface, which means the host microcontroller needs only one GPIO pin and a ground connection to read voltage, current, temperature, and remaining capacity — a significant wiring simplification in space-constrained portable products. The 10-WFDFN exposed-pad package with a 3x4 mm footprint suits compact PCBs where every square millimetre counts.

The ROHS3 compliance covers the current exemption set, no problem for EU-market builds.

Frequently asked questions

Can the DS2780G+ be used with a 2-cell Li-Ion battery?

No. The DS2780G+ is designed for a single series cell. A 2-cell pack would exceed the monitor's input voltage range. For a 2-cell application, look at the DS2782 or DS2784 family, which support multiple cells in series.
