MAX17330X22+T

Overview

The MAX17330X22+T is a single-cell battery charger and fuel gauge integrated circuit from the AccuCharge ModelGauge m5 EZ family. It combines charging management with state-of-charge monitoring in a compact package. The device supports lithium-ion and lithium-polymer batteries, providing precise current regulation and thermal management during the charging cycle.

Feature Summary

• Integrates ModelGauge m5 EZ algorithm for accurate state-of-charge estimation without requiring additional hardware sensors
• Supports programmable charging profiles including constant-current and constant-voltage stages with termination control
• Includes built-in thermal regulation to limit die temperature during high-current charging operations

Applications

• Portable medical devices requiring precise battery level indication
• Wearable electronics with limited board space
• IoT sensors and modules using single-cell lithium batteries

Procurement Notes

Verify the specific suffix X22 against the official Analog Devices datasheet to confirm pinout and feature set compatibility. Ensure the component source provides valid traceability documentation as per industry standards for power management ICs.

Selection Notes

Select this component when system design requires combined charging and fuel gauge functionality in a minimal footprint. Evaluate thermal performance requirements against the internal regulation capabilities before finalizing the bill of materials.

Part Context

This part belongs to the MAX17330 series, which integrates charge pump technology for efficient single-cell charging. The X22 suffix typically denotes a specific tape-and-reel packaging configuration or variant within the broader Maxim Integrated portfolio managed by Analog Devices.

Replacement Considerations

Consult the official cross-reference list for direct replacements such as other ModelGauge m5 variants. Verify electrical compatibility and software driver support before substituting with older generation fuel gauge ICs.
