Overview
The MAX17022ETA+T is a battery fuel gauge IC from the Analog Devices / Maxim Integrated portfolio. It utilizes ModelGauge m5 technology for accurate state-of-charge estimation. The device supports both 1-Wire and UART communication interfaces, facilitating flexible system integration. It is housed in an 8-TDFN (3x3 mm) surface-mount package. Designed for single-cell lithium-ion or lithium-polymer batteries, it provides essential monitoring data for portable electronics.
Feature Summary
- Integrates ModelGauge m5 algorithm for precise battery state-of-charge calculation
- Supports dual communication protocols including 1-Wire and UART
- Optimized for single-cell lithium-based battery chemistries
Applications
- Portable consumer electronics requiring accurate battery level indication
- Smartphones and tablets with single-cell power systems
- Wearable health devices needing compact battery management
Procurement Notes
Verify component authenticity through authorized distributors due to high counterfeit risk. Confirm the specific suffix matches the required package and temperature range. Check current lifecycle status as availability may vary by region. Ensure compatibility with existing firmware for 1-Wire or UART protocol selection before procurement.
Selection Notes
Select this part when a compact solution for single-cell battery monitoring is required. It is suitable for applications prioritizing accuracy over raw speed. Consider the interface requirements; choose between 1-Wire for pin-saving designs or UART for standard serial communication. Evaluate board space constraints against the small TDFN footprint.
Part Context
This component belongs to the MAX17022 family of fuel gauges. It shares architectural similarities with other ModelGauge-enabled devices but offers specific interface options. It serves as a dedicated monitoring solution within the broader power management ecosystem, focusing on data acquisition rather than power switching.
Replacement Considerations
Direct replacements include other MAX17022 variants with different suffixes for package or temperature adjustments. Cross-referencing with MAX17024 or MAX17025 may be necessary if additional features like coulomb counting are required. Verify pinout compatibility before substitution.
