It communicates over an I²C interface and integrates the fuel-gauge algorithm, voltage/current/temperature measurement, and protection features into a single 14-TDFN (3x3 mm) package with an exposed pad for thermal management. The part is rated for industrial temperature environments (-40°C to 85°C), making it suitable for outdoor telecom, portable instrumentation, medical devices, and power-tool battery packs where accurate state-of-charge reporting is required. ## Cell-count flexibility and interface The controller supports 2 or 3 series cells (2S or 3S configurations), which covers the majority of mid-voltage portable and backup battery packs. The I²C interface allows direct connection to a host MCU without additional level shifters if the host runs at the same logic voltage; the operating temperature range of -40°C to 85°C covers both cold-start and hot-chamber conditions in industrial and outdoor equipment. ## Package and mounting Housed in a 14-WFDFN with exposed pad (3x3 mm body), the MAX17205G+00E is a surface-mount device. The exposed pad must be soldered to a thermal land on the PCB for adequate heat dissipation during high-current charge/discharge cycles. ## Lifecycle and sourcing The MAX17205G+00E is listed as Active in production with ROHS3 compliance.","metaTitle":"MAX17205G+00E ModelGauge™ Multi-Function Controller","metaDescription":"MAX17205G+00E from Maxim Integrated (now Analog Devices) is an active ModelGauge™ multi-function controller for 2-3 cell Li-ion packs with I²C interface","metaKeywords":null},"attributes":{"series":"ModelGauge™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"ModelGauge™","Package":"Tray","Function":"Multi-Function Controller","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"14-WFDFN Exposed Pad","Number of Cells":"2 ~ 3","lifecycle_stage":"eol_hot","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"14-TDFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.98000","currency":"USD"},{"qty":10,"price":"$4.47100","currency":"USD"},{"qty":25,"price":"$4.22680","currency":"USD"},{"qty":80,"price":"$3.66325","currency":"USD"},{"qty":230,"price":"$3.47539","currency":"USD"},{"qty":490,"price":"$3.11847","currency":"USD"},{"qty":980,"price":"$2.63004","currency":"USD"},{"qty":2450,"price":"$2.49854","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8485a3550aa7c265ba2fac3b16f55cc4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MAX17205G+00E work with a 2S or 3S Li-ion battery?","answer":"Yes, the controller is specified for 2 to 3 series cells (2S or 3S Li-ion/Li-polymer packs).
