MAX17205G+

Overview

The MAX17205G+ is a stand-alone ModelGauge m5 fuel gauge IC designed for lithium-ion and lithium-polymer battery packs. It operates within a supply voltage range of 4.2 V to 20 V, with an output voltage of 3.4 V and output current capability of 50 mA. The device features a low operating supply current of 25 uA and functions reliably across a temperature range of -40°C to +85°C. Packaged in a TDFN-14 format, it provides accurate state-of-charge monitoring through advanced algorithmic measurement.

Feature Summary

• Implements ModelGauge m5 algorithm for precise state-of-charge estimation
• Supports standalone operation for single-cell lithium-based chemistries
• Integrates I2C interface for system communication

Applications

• Lithium-ion battery pack monitoring
• Lithium-polymer cell management systems
• Portable electronic devices requiring accurate fuel gauging

Procurement Notes

Verify the specific suffix 'G+' indicates lead-free status and RoHS compliance when sourcing. Confirm package type matches the TDFN-14 specification required for your PCB layout. Ensure compatibility with the host controller's I2C voltage levels before integration. Check manufacturer documentation for any recent lifecycle changes or obsolescence notices.

Selection Notes

Select this component for applications requiring high accuracy in state-of-charge reporting without complex external circuitry. It is suitable for designs where low quiescent current is critical for extending battery life. Consider the TDFN-14 package size constraints during mechanical design. Validate thermal performance within the specified operating temperature range.
