ADIMAX17048G+T10
Overview
The MAX17048G+T10 is a compact, ultra-low power 1-cell lithium-ion fuel gauge IC that uses the proprietary ModelGauge algorithm to estimate battery state-of-charge. Unlike traditional fuel gauges, it eliminates the need for a current-sense resistor, instead monitoring voltage to determine battery capacity. It features a high-accuracy measurement system with only 3uA of active operating current and a 0.5uA sleep mode, making it ideal for power-constrained portable electronics.
Why Choose This Part
The ModelGauge algorithm eliminates the need for current sensing and battery relearn cycles, simplifying the design and reducing BOM cost. Its extremely low 3uA current consumption ensures the monitor itself does not significantly drain small batteries. The device also features a programmable reset for battery swaps and a configurable alert indicator for low-battery conditions.
Applications
Key Specifications
Getting Started
Engineers can evaluate the device using the MAX17048EVKIT evaluation kit, which provides a hardware platform and software interface for testing the ModelGauge algorithm. Communication is handled via a standard I2C interface, requiring only two wires plus a ground connection to a host MCU. For software development, focus on configuring the alert thresholds and the hibernate mode entry/exit parameters to optimize power efficiency.
