MAX17335X22+T

Overview

The MAX17335X22+T is a single-cell battery management integrated circuit from the MAX173xx series, manufactured by Analog Devices Inc. (Maxim Integrated). It integrates an independent charger, fuel gauge, and protection functions with internal self-discharge detection. The device operates within a supply voltage range of 2.3 V to 4.9 V and features a quiescent current of 35 µA. It supports Lithium-ion and Lithium Polymer battery chemistries. The component is housed in a TDFN-EP-10 package designed for surface-mount installation. Operating temperatures are specified between -40°C and +85°C.

Feature Summary

• Integrates independent charging, fuel gauging, and protection functions into a single solution.
• Includes ModelGauge m5 algorithm technology for accurate state-of-charge estimation.
• Features internal self-discharge detection capability for enhanced battery monitoring.
• Supports multiple battery chemistries including Lithium-ion and Lithium Polymer.

Applications

• Portable consumer electronics requiring compact power management
• Wearable devices with space-constrained battery compartments
• IoT sensors utilizing single-cell lithium batteries
• Medical handheld devices needing reliable fuel gauge integration

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package marking and datasheet revision alignment before integration. Check regional supply restrictions as Mouser indicates non-sale in certain areas. Ensure thermal dissipation requirements match the TDFN-EP-10 package specifications during PCB layout design.

Selection Notes

Select this part when a combined charger, fuel gauge, and protection solution is required for single-cell applications. The 35 µA quiescent current makes it suitable for low-power portable systems. Consider the TDFN-EP-10 package size constraints against available board real estate. Verify compatibility with the specific lithium chemistry used in the target application.

Part Context

This component belongs to the MAX173xx family of battery management ICs. It shares architectural similarities with other ModelGauge-enabled parts like the MAX17260 and MAX17303. The integration of charging and gauging distinguishes it from standalone fuel gauges or chargers in the Maxim portfolio.
