Descriptions:

The MAX17205G+T is a low-power fuel gauge IC designed for single-cell battery applications. It provides accurate monitoring of battery voltage, current, and state of charge (SOC) using Maxim’s proprietary ModelGauge™ m5 algorithm. The IC is optimized for minimal power consumption, making it ideal for portable and IoT devices.

Features:

• ModelGauge™ m5 Algorithm: Combines short-term and long-term SOC tracking for high accuracy.
• Low Power Consumption: ~7µA active current, ~1.5µA standby.
• Programmable Alerts: Configurable thresholds for SOC, voltage, current, and temperature.
• Automatic Sleep Mode: Reduces power consumption when inactive.
• Small Footprint: 8-pin TDFN package for space-constrained designs.
• No Calibration Required: Factory-trimmed for immediate use.
• Supports Multiple Chemistries: Configurable for different battery types.

This IC is commonly used in smartphones, wearables, medical devices, and other battery-powered applications requiring precise fuel gauging.
