MAX17044G+T

Overview

The MAX17044G+T is a host-side fuel gauge system designed for dual-cell (2S) lithium-ion battery packs. It utilizes the ModelGauge algorithm to continuously track relative state-of-charge without requiring external current-sense resistors or battery relearn cycles. The device features precision voltage measurement with ±30mV accuracy up to 10.00V and provides data access via an I²C interface. It operates within a temperature range of -20°C to +70°C and is housed in an 8-pin TDFN package.

Feature Summary

• ModelGauge algorithm enables accurate relative capacity calculation without offset accumulation
• Eliminates the need for external current-sense resistors and full-to-empty battery relearning
• Supports both host-side and battery-side fuel gauging configurations
• Provides precise voltage measurement capabilities for dual-cell lithium-ion systems

Applications

• Smartphones and tablets
• Health and fitness monitors
• Digital still, video, and action cameras
• Medical devices
• Handheld computers and terminals

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm package integrity and pin alignment against datasheet specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Validate part marking against official manufacturer records to prevent counterfeit substitution.

Selection Notes

Select this component specifically for dual-cell lithium-ion applications requiring compact host-side integration. The absence of a sense resistor requirement reduces bill of materials cost and board space. Verify that the operating temperature range meets the specific environmental constraints of the target portable equipment design.
