Maxim Integrated DS2704RQC+T10 Battery Fuel Gauge IC

The DS2704RQC+T10 from Maxim Integrated is a high-precision battery fuel gauge integrated circuit (IC) designed to provide accurate monitoring of single-cell rechargeable battery packs. This compact and efficient IC is an ideal solution for portable devices where power management and monitoring are crucial for optimal performance and extended battery life.

Featuring Maxim's proprietary algorithms, the DS2704RQC+T10 offers precise state-of-charge (SOC) estimation and can handle various battery chemistries including Lithium-Ion (Li-Ion), Lithium Polymer (Li-Poly), and Lithium Iron Phosphate (LiFePO4). This versatility makes it a perfect fit for a wide range of applications such as smartphones, tablets, digital cameras, and other handheld devices.

The DS2704RQC+T10 integrates several key functions to ensure reliable battery management:

• Voltage Monitoring: The IC continuously monitors the battery voltage, providing vital data for SOC calculations.
• Temperature Measurement: An integrated temperature sensor allows for temperature-compensated charge tracking, which is essential for maintaining battery health and safety.
• Current Sensing: The device can measure charge and discharge currents, enabling accurate current flow tracking and SOC determination.
• Nonvolatile (NV) Storage: Important battery parameters and calibration data are stored in NV memory, preserving critical information even when the battery is removed.

Communication with the host system is achieved through a 1-Wire® interface, which simplifies the connection by using only a single wire for both power and data transfer. This interface also supports the unique ID function, allowing multiple devices to be individually addressed on the same bus.

The DS2704RQC+T10 comes in a compact, surface-mountable TQFN package, which is optimal for space-constrained designs. Its operating temperature range of -20°C to +70°C ensures reliable performance across various environmental conditions.

By integrating the DS2704RQC+T10 into your battery-powered solution, you can enhance the user experience through more accurate battery level reporting, prolong the life of the battery pack, and ensure the safety and reliability of your device.
