Maxim Integrated MAX17260SETD+T Fuel Gauge IC

The Maxim Integrated MAX17260SETD+T is a high-accuracy fuel gauge integrated circuit designed to provide precise monitoring of battery status in portable and wearable devices. This compact, power-efficient component utilizes Maxim’s patented ModelGauge™ m5 EZ algorithm, ensuring a robust and accurate state-of-charge (SOC) estimation without the need for battery characterization.

Key Features

• ModelGauge m5 EZ Algorithm: Offers a blend of smooth SOC tracking with robustness against battery diversity for most lithium batteries and applications.
• Low Operating Current: Its low quiescent current of 7µA (typ) in operating mode and 0.5µA (typ) in shutdown mode contributes to prolonged battery life.
• Adjustable Alert Thresholds: The IC provides programmable alert thresholds for voltage, temperature, current, and state of charge, facilitating proactive power management.
• High Accuracy: Delivers high SOC accuracy within ±5% under various conditions and does not require an empty or full battery recalibration.
• Easy to Implement: Comes in a tiny, lead-free, 12-pin TDFN package, making it suitable for space-constrained applications.
• Dynamic Power Estimates: The IC calculates remaining power capacity (mAh), time to empty, and time to full, providing comprehensive battery state information to the user.
