The MAX8556ETE is an integrated circuit (IC) component designed for battery charging and monitoring applications. It belongs to the MAXIM Integrated family of products and offers several key features that make it suitable for various portable electronic devices.
One of the notable features of the MAX8556ETE is its ability to charge a single-cell lithium-ion (Li+) battery efficiently. It supports charging currents up to 1.5A, which enables faster charging times. The IC incorporates a high-efficiency USB/AC-adapter detection circuit that allows it to automatically switch between USB and AC-adapter power sources.
The MAX8556ETE also includes a comprehensive set of safety features to ensure smooth and reliable charging. It integrates battery temperature monitoring and thermal regulation circuitry to prevent overheating during charging. The IC provides thermal foldback to reduce the charge current at high temperatures, protecting the battery from damage.
Furthermore, the MAX8556ETE features precise charge termination to protect the battery from overcharging. It monitors the battery voltage and current continuously, automatically terminating charging when the battery is fully charged. This feature helps extend the battery life and ensures safe operation.
The IC component also incorporates a programmable charge timer that limits charging time, preventing overcharging in case the termination circuitry fails
