Working Principles

The MAX1655EEE is a battery charger IC that utilizes a constant-current/constant-voltage charging algorithm. It regulates the charging current and voltage to ensure efficient and safe charging of batteries. The IC can be programmed to set various charging parameters such as charge termination voltage, preconditioning current, and thermal regulation thresholds.

When the charger is enabled, it monitors the battery voltage and adjusts the charging current accordingly. Once the battery reaches the programmed charge termination voltage, the charging process is terminated. The IC also incorporates thermal regulation to prevent overheating during charging.
