MAX17040X+T10

Overview

The MAX17040X+T10 is a compact, low-cost fuel gauge IC designed for single-cell or two-cell lithium-ion and lithium-polymer battery packs. It utilizes the ModelGauge algorithm to provide accurate state-of-charge (SOC) readings without requiring an external sense resistor. The device features an I2C interface for communication with host microcontrollers and operates within a specified temperature range.

Feature Summary

• Implements ModelGauge algorithm for high-accuracy SOC estimation
• Supports single-cell and two-cell battery configurations
• Enables system-level power management through precise monitoring

Applications

• Portable medical devices
• Industrial handheld terminals
• Smart sensors and asset trackers

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential supply chain variations. Confirm package integrity upon receipt as the WLP-8 form factor requires careful handling during assembly. Ensure compatibility with existing BOM specifications before finalizing procurement orders.

Selection Notes
