MAX17262REWL+T

Overview

The MAX17262REWL+T is a single-cell lithium-ion or lithium-polymer battery fuel gauge from Analog Devices. It utilizes the ModelGauge m5 algorithm to provide high-accuracy state-of-charge (SOC) and remaining capacity estimation without requiring battery characterization or calibration. The device integrates a 16-bit delta-sigma ADC, temperature sensor, and I2C interface for communication with host microcontrollers.

Feature Summary

• Implements ModelGauge m5 EZ algorithm for accurate SOC and remaining capacity tracking
• Integrates 16-bit delta-sigma ADC for precise voltage and current sensing
• Includes built-in temperature sensor and configurable protection logic
• Supports I2C communication with SMBus Alert interrupt capability

Applications

• Portable medical devices
• Industrial handheld terminals
• Asset trackers
• High-end consumer electronics

Procurement Notes

Verify the specific suffix REWL against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with the host system's I2C address configuration and voltage levels before integration.

Selection Notes

Select this component when high accuracy is required without battery modeling. It is suitable for applications needing reliable SOC data across wide temperature ranges. Consider the 9-WLP package size for space-constrained designs.

Part Context

Part of the MAX1726x family featuring ModelGauge technology. Designed as a drop-in replacement for older fuel gauges while offering improved accuracy and lower power consumption. Supports both standard and fast I2C modes.

Replacement Considerations

MAX17260SETD+T offers similar functionality in a TDFN package. MAX17260BEWL+T provides equivalent performance in a WLP package.
