Maxim Integrated MAX846AEEE+ Battery Management IC

The Maxim Integrated MAX846AEEE+ is a highly integrated battery management IC designed to simplify the construction of accurate and efficient chargers for lithium-ion (Li-ion) and nickel-metal hydride (NiMH) batteries. This compact, high-performance component is housed in a 16-pin QSOP package, making it ideal for space-constrained applications.

The MAX846AEEE+ offers a comprehensive solution for battery charging and management, featuring a constant-current/constant-voltage charge algorithm that ensures batteries are charged quickly and safely. Its versatility allows for use in a wide range of portable devices, including handheld computers, medical instruments, and consumer electronics.

Key Features:

• Automatic transition between charge states for efficient charging
• Programmable charge current for precise control over the charging process
• Prequalification of deeply discharged batteries to extend battery life
• Temperature monitoring to prevent charging at unsafe temperatures
• Charge status indicators to provide visual feedback during the charging cycle
• Low external component count for a simplified design and reduced system cost

The MAX846AEEE+ also includes various safety features to protect both the charger and the battery. These include overvoltage protection, to prevent damage to the battery if the input voltage exceeds safe levels, and a safety timer that limits the charge time to prevent overcharging. The IC also supports a top-off charge mode to ensure batteries reach their maximum capacity.

Designed with an emphasis on reliability and efficiency, the MAX846AEEE+ integrates seamlessly into battery-powered solutions, providing a robust charging solution that enhances the overall user experience by ensuring long battery life and optimal performance.

Whether you are designing a new product or upgrading an existing one, the Maxim Integrated MAX846AEEE+ offers the precision, flexibility, and reliability needed to create an effective power management system.
