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.
Temperature Grade and Environment
Rated for -20°C to 70°C (TA), the DS2780G+ fits commercial and indoor consumer applications — handheld instruments, power banks, IoT sensor nodes. The ROHS3 compliance covers the current exemption set, no problem for EU-market builds.
