It manages 2 to 3 series Li-ion cells and communicates over an I²C bus to a host microcontroller or PMIC. The ModelGauge algorithm combines voltage, current, and temperature measurements to estimate remaining capacity without the drift that plagues pure coulomb counters. Typical applications include portable medical devices, handheld industrial tools, and battery-backed instrumentation where accurate fuel-gauging extends run-time and protects the pack from deep discharge. ## Temperature range and environment Rated for -40°C to 85°C ambient, this controller suits industrial enclosures, outdoor telecom cabinets, and portable equipment that sees seasonal extremes. ## Lifecycle and sourcing reality The MAX17205G+ is an active, current-production part per Maxim's lifecycle records. ROHS3 compliant. For a BOM line that needs a fuel-gauge IC for 2–3 cell packs, this part is available to source through independent distribution; we confirm current pricing and availability at quote time against an RFQ. No official second-source or pin-compatible alternate is listed — the ModelGauge algorithm is proprietary to Maxim, so a drop-in replacement from another vendor does not exist.","metaTitle":"MAX17205G+ ModelGauge Multi-Function Battery Controller","metaDescription":"MAX17205G+ from Maxim Integrated is a multi-function battery controller using ModelGauge algorithm.
