Battery fuel-gauge IC for single-cell portable designs
The MAX17055ETB+T is a single-cell battery monitor from Analog Devices' ModelGauge series, handling multi-chemistry cells (Li-ion, Li-Poly, LiFePO4, etc.) over an I²C interface. Housed in a 10-WFDFN exposed-pad package (2.5 × 2 mm body), it mounts on the board with the thermal pad soldered to a ground plane for heat sinking — the pad is the primary thermal path, so the PCB layout must include a solid copper pour under the part.
Sourcing and procurement posture
The Tape & Reel packaging (TR) suits automated pick-and-place assembly; Cut Tape (CT) is also listed for prototype or low-volume builds.
