Product details

Single-cell fuel gauge with ModelGauge algorithm

The Maxim Integrated MAX17201G+ is a single-cell battery monitor from the ModelGauge series, designed to report state-of-charge and voltage via an I2C interface.

I2C readout and single-cell fit

Communication is over I2C, so the host MCU reads voltage and capacity data directly. The part is specified for one series cell — lithium-ion or LiFePO4 — and the ModelGauge algorithm compensates for temperature and discharge rate without requiring a current-sense resistor. That saves board area and BOM cost in single-cell handhelds, wearables, or IoT nodes.

It is ROHS3 compliant, so no Pb or restricted substances above threshold.

Frequently asked questions

Is the MAX17201G+ obsolete?

No, the MAX17201G+ is listed as active in production. There is no discontinuation notice or last-time-buy schedule in effect.

What is the difference between MAX17201G+ and MAX17201?

The MAX17201G+ is the lead-free, ROHS3-compliant ordering code variant of the base MAX17201. Functionally they are identical; the G+ suffix indicates the green/ROHS-compliant finish. For new designs, the G+ variant is the standard offering.

What is the MAX17201G+ used for?

The MAX17201G+ is a single-cell battery monitor used in portable electronics, handheld instruments, IoT devices, and industrial equipment that runs on a single lithium-ion or LiFePO4 cell. It provides accurate state-of-charge reporting over I2C without a current-sense resistor.
