Single-cell Li-ion fuel gauge with I²C
It is designed for portable and embedded systems where one Li-ion or Li-polymer cell powers the load — think handheld instruments, medical peripherals, or IoT edge nodes that run on a single 3.6 V to 4.2 V cell.
Industrial temperature rating — outdoor and enclosure duty
The 85°C ceiling covers most sealed-product hot spots without needing an automotive-grade part.
15-DSBGA — tiny footprint, careful layout
The 15-DSBGA (0.4 mm pitch, 2.3 mm × 1.7 mm typical) saves board area but demands a controlled solder-paste stencil and an X-ray inspection step during first-article build. The I²C lines need pull-up resistors sized for the bus capacitance; the supply decoupling cap should sit within 2 mm of the package edge.
