MAX17043X+T10

Overview

The MAX17043X+T10 is a compact, low-cost fuel gauge system for single-cell lithium-ion batteries. It utilizes the ModelGauge algorithm to track relative state-of-charge continuously without requiring battery relearn cycles or an external current-sense resistor. The device operates within a supply voltage range of 2.5V to 4.5V and features a UCSP-9 package. It provides precision voltage measurement with ±12.5mV accuracy up to 5.00V and communicates via an I2C interface.

Feature Summary

• Host-side or battery-side fuel gauging capability for single-cell applications
• Accurate relative capacity calculation using the ModelGauge algorithm
• Elimination of full-to-empty battery relearning requirements
• External alarm or interrupt functionality for low-battery warnings

Applications

• Smartphones
• Tablets
• Health and fitness monitors
• Digital still, video, and action cameras
• Medical devices

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance details prior to integration. Ensure the UCSP-9 package variant matches design constraints. Validate operating temperature specifications against environmental requirements. Check for obsolescence notices from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component for portable equipment requiring accurate state-of-charge tracking without complex calibration. The absence of a sense resistor reduces bill-of-materials cost and board space. Consider the MAX17044 if dual-cell (2S) configuration is required instead of single-cell operation. Evaluate thermal performance within the specified -20°C to +70°C operating range.

Part Context

This part belongs to the MAX17043/MAX17044 series of ultra-compact fuel gauges designed for handheld and portable electronics. It represents a host-side solution that simplifies battery management by integrating sophisticated modeling algorithms directly into the IC, reducing reliance on microcontroller processing power.
