Package and rework reality
The MAX17260SETD+T: Housed in a 14-TDFN (3x3 mm) exposed-pad package — the 14-WFDFN case code. The package is leadless with side wettable flanks, so it reflows cleanly with a standard hot-air profile for a 0.8 mm-thick board.
Single-cell Li-ion monitoring with I²C
This is a single-cell Li-ion battery monitor from the ModelGauge™ series, communicating over an I²C interface. It tracks state-of-charge, voltage, current, and temperature for one series cell — the number of cells is fixed at 1, so it's sized for portable devices, wearables, or single-cell power tools. The I²C bus runs at standard and fast-mode rates; no external ADC or coulomb-counter IC is needed because the monitor integrates the sense element and algorithm on-chip.
